Measuring relays and protection devices Part 121. Distance protection requirements1 ScopeGB/T 14598 provisions of this part of the general for, but not limited to effectively grounded three-phase power line distance protection work The minimum requirement for energy and performance evaluation. This section also specifies the way to record and publish performance test results. This part covers the distance protection functions whose operating characteristics can be defined on the impedance plane, including protection function specifications, measurement characteristics, selection Phase, Directionality, Startup and Delay Characteristics. This section includes test methods for testing performance characteristics and accuracy. This section specifies the accuracy of the factors under steady-state conditions And performance characteristics under dynamic conditions. This section also includes the protection requirements of the transformer. This section covers the distance protection functions are as follows. IEEE/ANSIC37.2 Function Code IEC 61850-7-4 Logical Node Phase Distance Relay 21 PDIS Ground distance relay 21G PDIS This section does not specify the additional functions normally associated with digital distance relays, such as oscillatory lockup (PSB), out of step tripping (OST), Voltage Transformer (VT) monitoring, closing in Fault Protection (SOTF), Accelerated Trip after Reclosing (TOR), Inactive Grounding Over-line fault protection logic in the network, trip switching logic. This section only deals with the impact of these additional features on distance protection. In series Compensation line protection beyond the scope of this section.
