一种改进功率硬件在环仿真稳定性与精度的接口算法
An algorithm of improving the stability and accuracy of the power hardware in the loop simulation
功率硬件在环仿真技术（Power Hardware In the Loop，PHIL）作为新兴的仿真技术，受到广泛的关注，其突出的可靠性与准确性已被证明是电力系统规划、设计、装置测试及新能源并网测试等方面的有效手段，然而稳定性与精度问题是PHIL仿真技术的关键指标，本文首先建立了千瓦级的PHIL仿真平台，建立PHIL仿真系统一阶线性的数学模型，分析其稳定性与精度，再根据几种不同的功率接口算法进行研究和比较。最终，提出一种合适的功率接口算法，通过仿真试验来验证所提出的功率接口算法的有效性与准确性。具有极强的工程使用价值，为硬件在环仿真技术的研究、发展提供了基本保障和良好的平台。
英文摘要:
Power Hardware In Loop simulation technology (PHIL) as a new simulation technology, has received widespread attention.Its reliability and accuracy have been proved to be the effective means of power system planning, design, installation testing and new energy grid test .The stability and accuracy of the question, however, is the key indicators of PHIL simulation technology.This paper first established the kilowatt PHIL simulation platform, then established a mathematic model of the first-order linear PHIL simulation system,and analysis of its stability and accuracy, according to several different power interface algorithm are studied and compared.In the end, a suitable power interface algorithm is put forward,Through the simulation test to verify the validity and accuracy of the algorithm of power interface.With a strong engineering use value for hardware in the loop simulation technology research, development, provides the basic security and a good platform.
