    摘要:

    在对某地区高压系统进行谐波分析时,由于高压电网的复杂性,使建模的复杂性和难度都大大增加。由此提出一种基于综合性电气分析计算软件ETAP建立简化模型的方案。首先在ETAP编辑界面按照地理位置搭建电力系统单线图,其次将实测数据录入模型并进行仿真分析。最后通过谐波分析,将仿真值与实测值的比较,允许两者误差在一定范围内,验证所采用发电厂、变电站等模型具有正确性、有效性。实际运行表明,该地区的模型简化方案切实可行。

    Abstract:

    Due to the complexity of the high voltage power grid, the complexity and difficulty of the modeling are increased greatly when the harmonic analysis is carried out for a certain area of HV system. Therefore, a simplified model based on the integrated electrical analysis software ETAP is proposed. Firstly, the single line diagram of the power system is built according to the geographical position in the ETAP editing interface. Secondly, the measured data is input into the model and simulated. Finally, harmonic analysis is used to compare the simulation and measured values, allowing both errors to be within a certain range, and the correctness and effectiveness of the models such as power plants and substations are verified. Results shows that the model simplification scheme is feasible.
