Generator & transformer protection configuration for 1000 MW unit of nuclear power station

WANG Zhaopeng(Electric Design Institute of Guangdong Province,Guangzhou 510663,China)  
The connection type and operating characteristics of 1000 MW nuclear power station are introduced and the configuration principle of generator transformer protection system is put forward :the dual-configured main protection should be enhanced and the backup protection simplified.According to the category of main protection and backup protection,their configurations are described,mainly including the differential protection,100 % stator grounding protection,over-excitation protection,loss-excitation protection,rotor grounding protection,etc.The protection principles and tripping actions of stator grounding protection,loss-of-excitation protection and rotor grounding protection are analyzed in detail.The 100 % stator grounding protection is based on external 20 Hz AC signal principle,the loss-of-excitation protection adopts admittance principle,and the rotor grounding protection applies the single terminal injection principle by periodic detection of insulation between rotor and earth.The interlocking protection of nuclei island system is described briefly,for example,the low speed protection of reactor cooling pump needs 500 kV circuit breaker for inter-tripping the unit into house generating operation.The P-series current transformer is selected for generator differential protection due to the space restriction and it is verified by calculation that 5P60 current transformer can satisfy its requirement for no-rejection.
