水轮发电机组进相运行水轮发电机组进相运行leading power factor operation of water turbine generator setshu一}unfodlonJ一zul}nxlong yunx一ng水轮发电机组进相运行(leading power faetoroperation of water turbine generator set)水轮发电机组处于欠励运行，以吸取电力系统刹余的容性无功功率又送出有功功率的一种运行方式。对于长距离送电的超高压、特高压线路，在轻负荷时，由于刹余容性无功功率，引起送电端电压上升，接近或超过电力系统运行电压的上限，严重地影响电力系统电压质量与安全运行。为降低此电压，可以采用并联电抗器来吸收电力系统剩余的容性无功功率，虽也能达到降低电压的目的，但设备投资较大，不如水轮发电机组进相运行简单、安全、经济、方便。水轮发电机组进相运行后，可以降低送端电压，节约电能，改善电网的供电质量，保证用户设备安全，提高电站经济效益.这是由于定子电压下降，转子电流下降，使水轮发电机的铁损也随之下降，转子铜损也降低，虽然此时定子铜损也相应增大，但综合的结果，发电机总损耗还是下降的，节能效果是明显的.水轮发电机组进相运行能力的大小，受其静态稳定极限、定子铁芯、定子端部金属结构件的温升和定子过电流的限制。更主要的是受电厂厂用母线电压限制。因此，按中国水利电力部1982年颁布的《发电机运行规程》规定:“发电机是否能进相运行，应遵守制造厂的规定，制造厂无规定时，应通过试验来确定”。水轮发电机组进相运行时，其励磁装t最好带电力系统稳定功能，或独立装设电力系统稳定装t(PSS)，这样可以提高静态稳定能力，即使在功角达到或超过90。时，机组仍能稳定运行，并且励磁电流的调节也很平稳。因此，水轮发电机组在电力系统负荷低谷时，采用进相运行，可改善电力系统电压质t。
