一种改进的二级电压控制模型研究

Study on Improved Model for Secondary Voltage Control

针对二级电压控制设备既有连续设备又有离散设备的特点,建立了改进型离散二级电压控制系统的数学模型。模型中增加了有载调压变压器等离散设备,同时考虑了二级电压控制区域间的影响以及无功控制设备端电压的偏离值,使得该模型更加符合实际的电力系统。

Because the control devices of the secondary voltage control have devices of continuous regulation and discrete regulation, the improved discrete model for secondary voltage control system has been built. Discrete regulation devices, such as on-load tap changers, have been added to the model. Taking into account the effect of the secondary voltage control regions and the departure value of reactive power control device terminal voltage, the model is more in line with the actual power system.
