摘要:
为解决分布式发电系统受配电系统馈线承载电流的影响，即无法在馈线任意位置加入并联运行的可再生能源系统，其可能影响可再生能源的广泛布置。利用相邻2个供电回路，在2个电力馈线间分别串接换流器，并令其共用直流电压汇流排，有助于提升主电力馈线的电压骤降保护，电力潮流也从副馈线转移到主馈线回路。以线间调度方式解决部分输电线路的承载量问题，进而提高电力系统的适应性。通过理论分析验证所提方法的可行性，为电力品质改善提供参考。
Abstract:
The distributed generation system is usually affected by the feeder current load of the distribution system. It is difficult to add the parallel operated renewable energy systems at any position in the feeder system, which may affect the broad distribution of the renewable energy system. In this research, the adjacent two power supply circuits were used, and the inverters were concatenated between two feeders. The unified power quality conditioner was not only operated for keeping the load voltage at constant in either of the two feeders, but also for transferring desired power between the bridged feeders. The line scheduling method was used to solve the problem of bearing capacity of part of the transmission line so as to improve the adaptability of power system. The feasibility of the proposed method was verified through the theoretical analysis, providing the references for improving power quality.
