摘要
针对部分区域无功分布不合理,引发线损高、电压质量差、电力系统稳定性差等问题的现状,提出了通过电力系统内部无功优化的方式来解决这些问题,建立了以线损最低和电压质量最好为目标函数的多目标无功优化模型,并以实际算例对数学模型进行验证,分析结果表明:模型能够有效降低线损,增强经济效益,提高电压质量,保证电力系统安全运行。
For the problems of high rate of line loss, po or voltag e quality and bad power stability of the power system caused by unreasonable reactive power distribution in some regions, this paper proposes the reactive power optimization to solve the problem. A multi-objective reactive power optimization model for the lower line loss and better voltage quality is constructed. The mathematical model is verified by examples. The analysis shows that the model can effectively reduce the line loss, enhance economic efficiency, improve voltage quality, and ensure safe operation of the power system.
