摘要
为实现电网电能质量的治理决策支持,提出了一种基于模糊专家系统的治理决策支持系统。针对目标电网存在的各种电能质量问题,使用成本效益分析方法对过界的电能质量指标及其对应的备选治理方案进行成本和效益两方面的经济性量化、评估,将电能质量指标以及经济性评估数据输入已构建的模糊专家系统,进行模糊推理、分析,输出目标电网电能质量治理的有效、经济推荐方案,以此达到系统电能质量治理方案的辅助决策支持功能。算例分析表明:将所提方法应用于电能质量治理决策支持具有良好的可行性,可以得到最优治理设备。
To realize decision support for power quality control in power grid, a decision support system based on fuzzy expert system is proposed. For all kinds of power quality problems existing in the distributed gird, the cost-benefit analysis method can be used to quantify and evaluate the economic costs and benefits for the overrun power quality indexes and the corresponding treatment schemes. When the input information including the power quality indexes and the cost-benefit analysis results are input into the established fuzzy expert system, the fuzzy inference can be carried out to output the effective and economical scheme for power quality control, which achieves the function of decision support for power quality control. Example analysis shows that the proposed decision support method for power quality control is feasible, the optimal control equipment can be obtained.
