渔子溪水电站的混流式水轮机设计水头270米,运行水头300米,投产后经多次关导叶压水调相试验,都因导叶漏水量过大无法实现。为了满足系统无功需要,多年来一直采用关导叶浸水调相和不关导叶的机组零功率因数运行方式。当采用浸水调相时,每发1亿度无功需消耗1,160万度有功,当采用机组零功率因数运行方式时,每发1亿度无功,除需耗水 Yuzixi Hydropower Station Francis turbine design head 270 meters, 300 meters head run, after many Guanyin Ye pressure water phase test, due to excessive leakage of guide vane can not be achieved. In order to meet the needs of reactive power system, over the years has been the use of the control of the leaves and leaves the water phase conditioning and non-related leaves zero power factor zero-power mode of operation. When using water phase modulation, each 100 million kWh of reactive power consumption to consume 11.6 million degrees of active, when the unit zero power factor mode of operation, each send 100 million degrees of reactive power, in addition to water consumption
