摘要
供电网中接入可再生能源的增加,提高了供电网负荷。为此,研究在考虑负载均衡度的基础上,设计一种供电网负荷自动均衡调度系统。在远程调度主站中分别配置后台中心网络和前置采集网,通过设计环网的通信网络结构实现通信功能,然后使用数据处理芯片处理供电网负荷调度数据。在设计负荷均衡调度模块后,结合SVR和小波分解设计供电网负荷预测算法。性能测试结果表明:在应用该系统后,供电和总负荷值之间的方差和均值较低,热功率平衡误差和风功率平衡误差较低,该系统的负荷均衡调度能力较强。
The increase of renewable energy in power supply network increases the load of power supply network.Therefore,based on the load balance degree,this study designs an automatic load balance dispatching system for power supply network.The communication function is realized by designing the communication network structure of the ring network,and then the data processing chip is used to process the load dispatching data of the power supply network.After the load balancing scheduling module is designed,the load prediction algorithm of power supply network is designed by combining SVR and wavelet decomposition.The performance test results show that the variance and mean value between power supply and total load are low,thermal power balance error and wind power balance error are low,indicating that the system has a strong load balance scheduling ability.
