Analysis of WDK-600 shunt reactor interturn protection;

A novel shunt reactor interturn protection scheme is proposed based on zero-sequence compensated voltage magnitude comparison.

This paper is prepared for main purpose of studying and discussing relative protection problems occurred in physical operation of power plant including mainly the problems happened during operation of high frequency protection passages, those in respect of interturn protections of generator and those regarding backup protections of self-shunt excitation generator.

Analysis of inter-turn protection in shunt reactor in ultra-high-voltage substation-used power system

Analysis on inter-turn protection in busbar high voltage shunt reactor

When only three leading terminals are provided in neutral side of a generator,the inter-turn protection usually consists of longitudinal zero-sequence voltage relay and directional negative-sequence relay based on fault component.

Retrofit of generator-transformer protection for 300 MW thermoelectric units;

Through introduction of circumstances of hardware failure of DGT-801 generator-transformer protection set because of halfway performing the countermeasure,leading to the whole set protection mal-operation,the causes are analyzed and countermeasures are put forward.

Its generator-transformer protection used WFB-100 microprocessor-based protection system developed by XJ group corporation.
