【摘要】 本文建立了电力系统无功优化的数学模型，并采用面向对象的编程思想，开发出了包含无功优化功能的电力系统分析类库。在优化计算中，实现了先进的性能优良的原－对偶内点算法，该算法收敛次数稳定，不随问题规模的变化而产生大的变动。该软件采用C++语言编写，在Windows平台上调试成功。程序运行最终结果给出了无功调整方案，包括发电厂电压控制、变压器分接头位置和电容器投切组数。最后对Ward-Hale 6节点系统和IEEE 30节点系统进行实例计算，证明了软件的正确性和有效性。更多还原

【Abstract】 A smart and efficient mathematic model of VAR Optimization has been built in this paper, and the author developed an electric power analysis class library that includes reactive power optimizer based on Object-Oriented technology. The advanced primal-dual interior point method is applied to solve optimal problem. It is seen that the method is of stable convergence and the times of iterations are not fluctuant with the influence of problem scale. The C++ language is used for the program, and it was debugged under windows environment. The results include generators’ voltages, transformers’ ratio and the volumes and location of compensating capacitor. At last, Ward-Hale 6 nodes system and IEEE 30 nodes system are used as the samples of the program, and the rightness and validity are tested through them.Li Li-ying (Electric Power System and Its Automation)Directed by prof.
