摘要
本文以控制电厂220kV母线电压在调度允许的合格范围为目的,通过分析计算,合理选取主变分接开关及高厂变、低厂变分接开关,最大限度发挥机组的无功调节能力。在高峰负荷时段,即使系统电压低于合格水平,机组能按机组最大无功出力进行调节;在低谷时母线电压高又能深度进相运行;同时能保证厂用电电压水平在允许范围。
Aimed to control the dispatch range of power plant 220kV bus, the paper choose the switch of transformer equitably by analysis and calculation, make the capacity of the generator adjusting var best. In peak time, the generator can adjust maximum of var even if the system voltage below wellformed voltage. In the low point, the bus voltage is high, and hold the admissible level.
