农村电网无功优化配置实用方法研究

电网的无功优化配置是一个多变量非线性有约束的最优化问题,求解方法比较复杂,农网技术人员在实际工作中迫切需要这方面的实用化方法。为此进行研究,推导和简化了等网损微增率准则和最优网损微增率准则,提出了几种实用有效的计算方法,并在此基础上开发了无功优化计算软件包。这些方法概念清晰,计算简便,便于农网技术人员学习使用。文中提出的无功优化模型和算法,经实际系统验证得到令人满意的效果,证明了模型和算法的合理性和有效性。

Research on Applied Methods of Optimal Distribution of Reactive Power Compensation in Rural Power Systems

Optimal distribution of reactive power compensation is a multi-variant,nonlinear and constrained optimization issue and is difficult to calculate.Engineers of rural power grid need applied methods in this area badly.Several practical and efficient methods are proposed in this paper.Equal network loss ratio and optimal network loss ratio are deducted and simplified.On the basis of the methods mentioned above,optimization software on reactive power distribution is developed.Methods proposed in the paper are easy to be mastered for technical experts of rural power network.Rationality and effectiveness of the mathematic model are proved through the computation in real practice and good results are obtained.
