采用了基于预控扫描的灵敏度分析方法和设备控制费用评估技术 ,建立了综合考虑电压、网损、功率因数、设备控制费用等因素的数学模型 ,实现了对电压的矫正和网损的优化 ,同时 ,很好地控制了功率因数 ,减少了设备的控制次数。该优化控制系统在厦门地区电网应用 ,其经济和社会效益均较显著。 The sensitivity analysis method based on pre-control scanning and device control cost evaluation technology are adopted. The mathematical model considering voltage, network loss, power factor, equipment control cost and other factors is established. The rectification of voltage and optimization of network loss are realized. At the same time, good control of the power factor, reducing the number of control equipment. The optimal control system in Xiamen power grid applications, the economic and social benefits are more significant.
