摘要
负荷模型和参数是电力系统仿真四大模型和参数之一,对整个系统仿真的各方面影响不言而喻。在全国各电网深入开展系统仿真研究的同时,各电网公司联合高校和科研院所进行了一系列的理论和试验研究,如东北电网人工三相短路试验,取得了不少成果。上海市电力公司在负荷特性建模和参数辨识方面,根据上海电网自身特点,提出、实践和验证了诸多新方法,进行了一系列理论研究和试验工作,结果表明采用人工小扰动的综合测辨法、利用故障录波仪量测数据、不对称故障数据用于负荷建模等新思路是切实行可行的,具有经济效益。
Load model and parameters are one of the four kinds of models and parameters in electric power system simulation, which are obviously important to the whole system simulation. When power system simulation research is popularly carried out all over the country, many power grid companies implement a series of theory research and experiment on load modelling and many results are attained such as three-phase shorted circuit tests in northeast China power grid. According to itself characteristics, Shanghai Municipal Electric Power Company make out, practise and proof some novel methods in load modeling and parameters recognition. The research and experiment results show that man-made small disturbance tests, measuring data by disturbance recorder ,usage of unbalanced fault data are practical, effective and economical to power system.
