中文摘要：

现有的试验电源电能质量模拟类型不完善，在总结提炼前人研究成果的基础上，提出试验电源电能质量模拟类型的分类，即基于波形特征的电能质量模拟和基于电网等值模型的电能质量模拟。进而，针对试验电源在电能质量模拟时缺乏理论基础，提出采用相似理论指导试验电源的电能质量模拟，以使试验电源模拟出与电力系统相似的电能质量现象。为了评价试验电源的电能质量模拟效果，基于相似理论提出相似程度d这一指标，用来评价试验电源模拟的电能质量与“原型”的相似性，从而判断电能质量模拟效果是否可信。最后，通过仿真验证所提指标的可行性。

英文摘要：

As the existing testing supply is imperfect in the power quality simulation, on the basis of summing up the results of previous relevant studies and further thinking, this paper proposes a new classification of the testing supply power quality simulation types, namely power quality simulations based on the wave characteristics and equivalent model of power grid respectively. Furthermore, as the theoretical support is not complete for the power quality simulation for the testing supply, the paper proposes to use the similarity theory to guide power quality simulation so that the testing supply can simulate the power quality of the power system.In order to evaluate power quality simulation results or judge power quality simulation credibility, similarity degree d is proposed as an index to evaluate the similarity between power quality simulated by testing supply and the prototype. Finally the feasibility of the proposed index is verified by simulations.
