基于AVC技术的配电网电压多级协同控制策略研究

Research on multi-level collaborative control strategy of distribution network voltage based on AVC technology

随着经济的发展和电力网络的不断扩大,电压越限时间长和无功补偿设备动作过于频繁,地区电力负荷迅速增长,随之而来的便是配电网络承载的输送电路很容易出现问题,从而影响用电用户的用电质量。在自动电压控制(AVC)理论的基础上,以湛江地区的配电网为研究对象,构建了全局AVC控制网络,提出了配电网络电压多级协同控制方法,采用模糊聚类算法来预测负荷的变化,最后在MATLAB/Simulink电力建模仿真平台搭建了基于模糊聚类算法的电压多级协同控制模型,试验证明该协同控制策略提升整个配电网络的响应速度和自动化程度。

With the development of the economy and the continuous expansion of the power network,the voltage over time and the reactive power compensation equipment are moving too frequently,and the regional power load is rapidly increasing.It is followed that the transmission circuit carried by the distribution network is prone to problems,thereby affecting the quality of electricity used by users of electricity.Based on the theory of Automatic Voltage Control(AVC),the distribution network of Zhanjiang area is taken as the research object,and the global AVC control network is constructed.The multi-level coordinated control method of distribution network voltage is proposed.The algorithm is used to predict the change of load.Finally,a voltage multi-level collaborative control model based on fuzzy clustering algorithm is built on the MATLAB/Simulink power modeling and simulation platform.The experiment proves that the collaborative control strategy improves the response speed and automation of the entire distribution network.
