摘要
Matpower具有强大的潮流计算功能,可通过对电力系统的潮流计算来获得电网电压。以新英格兰IEEE 39节点系统标准算例为测试对象,通过Matpower开展电网电压研究,对调节励磁电流以改变发电机端电压、适当选择变压器变比、并联电容器无功补偿等调压措施进行仿真,实现实际电网电压的优化调整。仿真结果表明,这些措施均能有效调整实际电网电压,为电力系统的稳定运行与发展提供重要依据。
Matpower is a simulation software with powerful power flow calculation function,and the power grid voltage can be obtained by power flow calculation of power system.In this paper,the grid voltage research is carried out based on the New England IEEE 39 node system standard example.The voltage regulation measures such as adjusting excitation current to change generator terminal voltage,properly selecting transformer transformation ratio and shunt capacitor reactive power compensation are simulated to realize the optimal adjustment of actual grid voltage.The simulation results show that these measures can effectively adjust the actual grid voltage and provide an important basis for the stable operation and development of the power system.
