合理分配且适量供给的无功功率对提高电网稳定性以及降低电网有功功率的损耗起到很重要的作用,并且调节无功功率分布最直接的目的在于稳定电压、改善电压波形、减少由于无功分配不合理导致过电压对设备绝缘所造成的影响。通过采用粒子... 合理分配且适量供给的无功功率对提高电网稳定性以及降低电网有功功率的损耗起到很重要的作用,并且调节无功功率分布最直接的目的在于稳定电压、改善电压波形、减少由于无功分配不合理导致过电压对设备绝缘所造成的影响。通过采用粒子群算法和数据包络分析法(DEA)对系统无功功率进行优化计算,从提高机组运行无功传输经济效率的角度进行分析,将提高机组运行无功传输经济效率与降低有功损耗并重,从而验证对电网系统所作无功优化计算在降低系统网损和提高机组运行无功传输经济效率方面具有双重指导意义。 展开更多

As the share of photovoltaic power generation in power system has increased year by year, the optimization choice of access system schemes become one of the first and most important problems in grid before admitting photovoltaic power generation. Therefore, this article takes a proposed distributed photovoltaic as an example to research and analyze two kinds of high density multiple access points distributed photovoltaic access system schemes. The emphasis is making a comprehensive comparison and selection among the aspect of active power loss and economic benefit, etc. In the premise of ensuring the normal power generation of the photovoltaic system, it puts forward the recommended scheme that can help to spontaneous self-consumption, elimination on the spot, effectively decrease network loss and economic benefit. 展开更多
