摘要:
The increased interest in using Ultra-High-Voltage
(UHV) transmissions has stimulated research in UHV operation
characteristic and correlative relay protections. Operational
experience in UHV is limited and hence there is a need to model
UHV transmission systems and test the operational performance
of traditional protection devices already in use on High-Voltage
(HV) and Extra-High-Voltage (EHV) systems. This paper presents
the development of a test environment based on a Real-Time
Digital Simulator (RTDS) of a UHV power system model and the
results of testing a distance relay using the model. It reveals that
the protective zone will be enlarged in the UHV system with shunt
reactor compensation and reduced without the compensation. To
resolve these issues further investigation is needed and ways of
resolving them, including the development of new algorithms,
should be examined.
