摘要
田湾河水电站采用六喷六折冲击式水轮机调速器,运行过程中存在调节负荷速度慢、在喷针切换过程中负荷波动较大的问题。针对上述现象分析产生的原因,探讨改进措施,用以改善调速器的调节特性,满足电力系统的要求。
Tianwanhe Hydropower Stations uses impulse turbine speed-governing system with 6 needles and 6 deflectors. In its operation, the load adjustment speed is slow, with wide fluctuation margin of load in the process of nozzle needle cut-over. This thesis makes an exploration on the causes of such problems and discusses measures of improvement in order to upgrade the adjustment property of speed-governors to fulfill the demand of power system.
