Abstract

The recent modification in utilizing Multifunction Power Conditioner (MPC) such as Unified Power Quality Conditioner devices in power systems has led to different degrees of power losses, owing to electronic power impacts. This paper presents a detailed comparison of power loss analysis in various configurations of MPC, that is, the conventional unified power quality conditioner (UPQC) and the UPQC with distributed generation (〖UPQC〗_DG). The independent losses based on inverter design and distributed generation interfacing to the distribution form the basis for each configuration case. The investigation considered conventional UPQC as the base case for power losses, and the study was extended to 〖UPQC〗_DG at steady state operating condition. In all configurations, Switching Losses (SL) and conduction losses were considered using simulation studies carried out in MATLAB/SIMULINK, and the results obtained in all cases were used for comparative studies. Finally, the outcome indicates that the losses in 〖UPQC〗_DG is more than conventional UPQC based on simulation results in all cases.

多功能电力调节器设计中分散发电的功率损耗分析提高电能质量

最近在电力系统中使用多功能电源调节器(MPC)，如统一电能质量调节器设备，由于电子功率的影响，导致了不同程度的功率损耗。本文详细比较了不同配置的MPC，即常规统一电能质量调节器(UPQC)和带分布式发电的UPQC(〖UPQC〗_DG)的功率损耗分析。基于逆变器设计的独立损耗和分布式电源与配电的接口构成了每个配置案例的基础。本研究以传统UPQC为基本工况，将研究范围扩展到稳态工况下的〖UPQC〗_DG。在所有配置中，通过MATLAB/SIMULINK进行仿真研究，考虑开关损耗(SL)和导通损耗，并将所有情况下得到的结果用于对比研究。仿真结果表明，在所有情况下，〖UPQC〗_DG的损耗均大于常规UPQC。
