摘要
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,使得该模型更加符合实际的电力系统。在Matlab环境下用经典的新英格兰39节点系统进行仿真,结果表明:与传统的二级电压控制相比,在增加了有载调压变压器等离散控制设备后的二级电压控制的效果明显提高。
In allusion to the characteristic of secondary voltage control devices provided with continuous regulation and discrete regulation,the improved discrete model for secondary voltage control system was built up.The discrete regulation device,such as on-load tap changing transformer,was added to make the model be more in line with the actual power system.The proposed method was applied to the New England 39 nodes system in Matlab platform.The simulation result shows that compared with the traditional secondary voltage control,this method can achieve great control effect by using discrete regulation devices such as on-load tap changing transformers.
