Abstract: The signal "springstored energy is abnormal" was given out frequently by the breaker spring storage operation mechanism in Jinshuitan Hydropower Plant.The three states indicated by the signal "springstored energy is abnormal" were analyzed. The signal processing flow of programable logic controler(PLC) was optimized, and the handling plan for improving the signal "springstored energy is abnormal" was proposed.

Key words: spring-stored energy is abnomal, analysis, handling plan
