irectional zone ne (b) Revers erse zone Figure Mho-based sed Character teristics Forward zones can be configured such that the reactance line takes a negative gradient when the terminal is sending power, which prevents the forward zone from overreaching for remote end faults combined with high load current The suitability of a distance relay for application to short lines is not determined by its minimum setting but rather by its measuring accuracy for high SIR conditions GRZ200 provides highly accurate measuring elements suitable to be applied to short lines By combination of multiple forward zones, GRZ200 can provide time-stepped distance backup protection for remote end busbars and adjacent lines Command Protection The following four schemes are available for distance protection using telecommunication - Permissive Underreach Protection (PUP) - Permissive Overreach Protection (POP) - Unblocking Overreach Protection (UOP) - Blocking Overreach Protection (BOP) To ensure that GRZ200 can provide reliable time-delayed tripping for close-up three-phase faults, the phase fault elements are reverse offset Reverse zones are used for local back-up protection for busbar faults or transformer faults POP and UOP are equipped with echo logic and weak infeed tripping functions and can be used in the protection of lines with weak infeed or no infeed terminals An undervoltage element is incorporated for the weak infeed tripping function The non-directional zone is used for time delayed backup protection covering all zones Zone1 Extension When telecommunications cannot be applied, a Zone extension (Z1X) protection is provided for high-speed protection of any fault along the whole length of the protected line GRZ200 provides dedicated distance zones (ZCSF, ZCSR) for command protection ZCSF is applied for forward faults and ZCSR for reverse faults In case that GRZ200 is applied using integral digital communication channels by fibre-optic links, or by electrical interfaces to a digital communication network, phase-segregated command protection is supported Earth Return and Mutual Coupling Compensation Distance zone protection for earth fault protection adopts vectorial zero sequence current compensation to eliminate distance measuring errors due to the earth return of zero sequence current Switch-on-to-fault Protection and Stub Protection When GRZ200 is applied to a double circuit line, in order to eliminate the influences of zero sequence mutual coupling, the zero sequence current for the parallel line can be introduced Reverse zones are not provided with zero sequence mutual coupling compensation for the parallel lines Switch-on-to-fault (SOTF) protection is provided in order to detect faults that are present when a line or busbar is energized For 500 ms following circuit breaker closure, this function is effective to protect against any switch-on-to-fault A non-directional overcurrent element and/or distance measuring elements perform the SOTF protection Load encroachment element characteristic To prevent the unwanted operation of the distance protection during heavy load flow, GRZ200 provides a load encroachment element Stub protection operates for a fault in a stub zone using an overcurrent element Application to Long and Short Lines Power Swing Blocking The large capacitance of a long transmission line can adversely affect the measurement of fault impedance GRZ200 employs an advanced charging current compensation technique which gives significant improvement in impedance measurement for long transmission lines GRZ200 provides a power swing blocking (PSB) function to prevent false tripping by distance measuring elements during a power swing When a power swing is detected, all distance protection zones and protection using characteristics as shown in Figure The element operates when the out-of-step locus passes from Zone A Zone B Zone C (or Zone C Zone B Zone A) and remains in Zones A and C for the detection time (TOST) telecommunications can be blocked independently When a zone is set to non-directional, the zone is not blocked A power swing condition is detected using two PSB elements with quadrilateral characteristics shown in Figure The outer PSB element PSBOUT encloses the inner element PSBIN, the two elements being separated by a width of PSBZ Further, GRZ200 provides PSBSZ and PSBGZ for phase fault measuring elements and earth fault measuring elements respectively Their functions and characteristics are identical PSBGZ provides phase-segregated characteristics X OSTXF Zone C OSTR2 Figure Characteristics element of out-of-step trip GRZ200 provides non-directional and directional overcurrent protections with inverse time and definite time for both phase faults and earth faults Inverse time overcurrent protection consists of an IDMT (inverse definite minimum time) element IDMT is available in conformity with the IEC 60255-151 standard which encompasses both the IEC and IEEE/ANSI standard characteristics Alternatively, a user-configurable curve may be created X PSBZ R Non-directional and Directional Overcurrent and Earth Fault Protection GRZ200 can provide high speed tripping for faults which occur during a power swing condition, by utilising a well-proven, dedicated negative sequence directional element and any of the PUP, POP, UOP and BOP command schemes PSBOUT The IDMT element has a programmable reset feature, selectable for instantaneous, definite time or dependent time operation This feature can be used to protect against flashing/intermittent fault conditions, or to grade correctly with electromechanical overcurrent relays R PSBZ OSTR1 OSTXB If the impedance locus enters the PSBZ zone for more than a predetermined time (20 to 100ms), the PSB function will block the selected zones The PSB function is reset after 500 ms when the impedance locus has moved outside the PSB elements PSBIN Impedance locus Zone A Zone B PSBZ PSBZ PSBZ: Impedance setting of PSB element Definite time overcurrent protection is enabled by the instantaneous overcurrent element and pickup-delay timer Figure Characteristics of power swing blocking element Tripping by each element can be disabled by the scheme switches, and overcurrent backup protection can be blocked by a binary input signal OC guard scheme for distance protection Each distance measuring element can be supervised by an independent overcurrent element GRZ200 can also provide non-directional and directional earth fault protection Protection functionality is the same as for the phase fault elements Out-of-step Trip Protection The out-of-step tripping function is used to execute power system separation at the optimum point when an out-of-step condition occurs The directional earth fault elements have a user selectable minimum voltage threshold An out-of-step condition is detected by using two impedance measuring elements with quadrilateral GRZ200 can provide directional earth fault command protection by using two stage directional earth fault elements, one of which is for tripping and the other is for blocking or for current reversal detection with high-speed reset time is used to prevent a spurious re-trip or back-trip following a successful trip or re-trip action Non-Directional and Directional Sensitive Earth Fault Protection Broken Conductor Detection The unbalance condition caused by an open circuited conductor is detected by the broken conductor detection function An unbalance threshold with programmable definite time delay is provided GRZ200 provides non-directional and directional earth fault protection with more sensitive settings for use in applications where the fault current magnitude may be very low Thermal Overload Protection The sensitive earth fault element includes a digital filter which rejects all harmonics other than the fundamental power system frequency The thermal overload feature provides protection for cables and other plant against the effects of prolonged operation under excess load conditions A thermal replica algorithm is applied to create a model for the thermal characteristics of the protected plant The characteristics are exponential functions according to functional standard IEC 60255-149 and take into account the I2R losses due to the specific operational current and the simultaneous cooling effect of the coolant In this way the tripping time during an overload condition takes the prior level of load current into consideration An alarm can be set to operate before the tripping condition is reached The sensitive earth fault quantity is measured directly, using a dedicated core balance earth fault CT Non-directional and Directional Negative Phase Sequence Overcurrent Protection Negative phase sequence overcurrent (OCN) protection can be used in applications where certain fault conditions may not be detected by the normal phase and earth overcurrent protections, for example, in the case of a relay applied on the delta side of a delta-star transformer, to detect an earth fault on the star side Alternatively, OCN can be used to protect a three phase motor against the severe overheating which results from operating with an unbalanced supply Thermal image: I2 - Ip2 t =τln I - (k IB)2 where t: Operating time τ: Thermal time constant I: Overload current IB: Thermal overload current setting K: Constant Ip: Specified load current before overload occurs The negative phase sequence overcurrent elements can be directionalized by polarizing against the negative phase sequence voltage Phase Undercurrent Protection Protection against loss of load is provided by the phase undercurrent protection Two independent stages are provided, each with a programmable definite time delay Breaker Failure Protection the Overvoltage Protection When an overcurrent element remains in operation longer than a pre-determined length of time following the output of a trip signal the associated circuit breaker is judged to have failed and adjacent circuit breakers can be tripped as a back-up measure GRZ200 provides two independent overvoltage protections for phase-to-neutral voltage input GRZ200 also provides two independent overvoltage protections for phase-to-phase voltage input All stages can be set for inverse time or definite time operation In total, therefore, GRZ200 provides four independent overvoltage thresholds Two independent timers are available, one of which can be used to control the RETRIP of the original circuit breaker(s) The second timer is used to control the back-tripping of adjacent circuit breakers For high-speed protection, an overcurrent element Undervoltage Protection Undervoltage Inverse Time Curves Overvoltage Inv erse Time Curves 1000.000 1000.000 GRZ200 provides two-stage undervoltage protection for phase-to-phase voltage input and two-stage undervoltage protection for phase-to-neutral voltage input The undervoltage protection is provided with an undervoltage blocking function to prevent undervoltage tripping in the case of a dead line 100.000 10.000 TMS = 10 TMS = Opera ting Tim e (se cs) Operat ing

Protection Figure Inverse time characteristics GRZ200 provides over/under frequency protection and frequency rate-of-change protection Zero Phase Sequence Overvoltage (Neutral Voltage Displacement) Protection These protections provide independent frequency protection stages The over/under frequency protection is programmable for either under- or over-frequency operation, and each has an associated DTL timer The frequency rate-of-change protection calculates the gradient of frequency change (df/dt) Neutral voltage displacement (NVD) protection is provided for detection of earth faults in high impedance earthed or isolated systems NVD can be programmed with definite time delays, and one stage is also available with an inverse delay The zero sequence voltage may be derived from the phase voltages, or directly measured Suppression of superimposed 3rd harmonic components of the supply voltage is included Negative Phase Protection Sequence Inrush Current Detector The inrush current detector is used to prevent an incorrect operation of overcurrent protections from a magnetising inrush current during transformer energisation Inrush current detector (ICD) detects second harmonic inrush current during transformer energisation Overvoltage For detection of unbalanced supply voltages, Negative Sequence OVN overvoltage thresholds are available, both of which can be programmed with definite time delays, and one is also available with an inverse delay Positive Phase Protection Sequence Cold Load Protection The cold load function modifies the overcurrent protection settings for a period after energising the system This feature is used to prevent unwanted protection operation when closing on to the type of load which takes a high level of current for a period after energisation Overvoltage To detect an overvoltage condition on a steady state, positive phase sequence overvoltage is provided The overvoltage condition is observed for a light-loaded long transmission lines of which capacitance is large, and it is also recognized as so-called Ferranti-effect Series reactors are normally installed for reducing the effect of capacitance, however, when the series reactor is not functioning, the network must be tripped for preventing further damages CONTROL Autoreclose Most faults on HV and EHV overhead transmission lines are transient faults, which are removed following line de-energization After a short time, the hot gases disperse and the air de-ionizes After clearing the fault θ: and deionizing the fault arc, reclosing can be performed GRZ200 provides two autoreclose schemes, single-shot autoreclose and multi-shot autoreclose synchronism check angle setting TSYN: synchronism check timer setting GRZ200 autoreclose function can be initiated by any of the following high-speed protections - Protection using telecommunication - Distance zone is set to zone extension VL θ deg VB θ θ Single-shot autoreclose OV θ Single-shot reclosing can provide any of three autoreclose modes; single-phase autoreclose, three-phase autoreclose, and single- and three-phase autoreclose Figure Synchronism check element One-and-a-half Breaker Scheme GRZ200 performs two-breaker autoreclose in a one-and- a-half breaker scheme Only single-shot autoreclose is available in a one-anda-half breaker scheme Single-phase autoreclose, three-phase autoreclose or single and three-phase autoreclose can be applied to the two circuit breakers In the three-phase autoreclose mode, all three phases are tripped, and then reclosed regardless of the fault mode, whether a single-phase fault or a multi-phase fault has occurred Switchgear Control In the single- and three-phase autoreclose mode, the single-phase is reclosed if a single-phase is tripped and the three phases are reclosed if three phases are tripped GRZ200 provides functions for local control of switchgear from the HMI Two-stepped operation (select-control) is applied for the control of circuit breakers, isolator switches and earthing switches Multi-shot autoreclose Also, switchgear control commands from the station level can be performed through GRZ200 within the application of a substation automation control system In multi-shot autoreclose, two- to four-shot reclosing can be selected The first shot is selected from any of the four autoreclose modes available in the single-shot autoreclose scheme Interlock check The interlocking function blocks the operation of primary switching devices, for instance when an isolator switch is under load, in order to prevent equipment damage and/or accidental human injury If reclosing by the first shot fails, three-phase tripping and reclosing is applied for the second to fourth shots Synchronism Check Each switchgear control function has interlocking modules included for different switchyard arrangements, where each function handles interlocking for one bay The interlocking function is distributed to each IED and is not dependent on any central function For the correct operation of three-phase autoreclose, voltage and synchronism check are necessary Characteristics of the synchronism check element are shown in Figure A detected slip cycle is determined by the following equation: θ 180°ХTSYN where, f: Operating zone UV In the single-phase autoreclose mode, only the faulted phase is tripped, and then reclosed if a single-phase
