漫湾电站250MW 水轮发电机组是我公司自行研制的高水头,混流式水轮发电机组,对漫湾电站~#4水轮发电机组进行进相试验,制定出发电运行容量限额图(P—Q曲线),一方面可以了解相同型号机组的特性,另一方面将试验结果提供给运行部门,对各级运行人员掌握机组特性,正确调整系统无功分布及改善电网电压质量具有重要的意义。 Manwanwan 250MW hydroelectric generator set is a high-head and Francis turbine developed by our company. The phase test of Manwan Hydropower Station ~ # 4 hydro-generating set is carried out, and the power generation capacity quota (P- Q curve). On the one hand, it can understand the characteristics of the same type of unit. On the other hand, the test results can be provided to the operation department. It is of great significance to the operation personnel at all levels to master the unit characteristics, correctly adjust the reactive power distribution and improve the voltage quality of the power grid.
