摘要
在移动电站供电的独立电力系统中,负载的冲击会造成电能质量的恶化,因此动态负载下的电气特性是移动电站的关键性能指标。针对目前测试平台评估指标不全面,测试方法落后的问题,建立了移动电站仿真系统,对中小功率移动电站常采用的谐波无刷同步发电机励磁系统与电子调速系统进行了建模,并对两类动态负载下移动电站的动态特性进行仿真分析。仿真结果表明所建模型可以用于移动电站动态特性的研究,采用的评估指标可以较好的评估移动电站性能,为研制移动电站测试用电子负载提供了依据,对于进一步优化电站试验平台检测技术具有重要意义。
In an independent power system of a mobile power station,the impact of the load will cause deterioration of the power quality.Therefore,the electrical characteristics under dynamic load are key indicators of the mobile power station.In view of the problems that the evaluation indicators of the current test platform are not comprehensive and the test method is outdated,this paper established a test simulation system for mobile power station to model the harmonic excitation system and digital speed control system,and simulate the dynamic characteristics under two kinds of dynamic loads.The simulation results show that the proposed model can be used to study the dynamic characteristics of mobile power stations.The adopted evaluation indicators can better evaluate the performance of mobile power stations,and provide a basis for the development of electronic load in the future.
