摘要
无功功率合理优化可以降低网损,提高系统运行经济性。本文基于灵敏度分析提出无功功率优化方法,可以快速调节系统无功功率,方法简单有效。通过计算各无功可调节点对网损的实时灵敏度,根据灵敏度计算结果调节无功功率,可以有效减少系统有功网损。最后,通过某实际系统算例验证了本文方法。
Reasonable optimization of reactive power can reduce network loss and improve system operation economy.Based on sensitivity analysis,this paper proposes a reactive power optimization method,which can quickly adjust the reactive power of the system,and the method is simple and effective.By calculating the real-time sensitivity of each reactive power adjustable node to the network loss and adjusting the reactive power according to the sensitivity calculation results,the active power network loss of the system can be effectively reduced.Finally,the method is verified by a practical system example.
