电网供电负荷均衡自动调度监测仿真研究

Simulation Research on Automatic Dispatching Monitoring of Power Supply Load Balancing

对配电网供电负荷调度的监测,能够有效改善电网供电数据拥塞现象。对供电负荷均衡调度的监测,需要先对配电网单通道数据进行分组采集,输出单通道数据信号幅值匹配倍率,完成负荷均衡自动调度。传统方法描述配电网系统的形式化规格,对配电网系统的可达性进行分析,但忽略了获得数据信号幅值匹配倍率,导致监测精度偏低。提出能够实现单通道分组数据平衡的数据采集路由机制,对供电负荷均衡自动调度进行监测。以单通道分组数据节点排队队列长度作为决策参数组建路由度量模型,以度量值最小为决策条件设计了单通道分组数据采集路由机制。通过自动调整单通道分组数据采样周期、数据采集输入调整倍数以及分组数据重构输出匹配倍率,实现负荷均衡调度监测。实验结果表明,上述方法可以有效改善单通道数据拥塞问题,数据采集速率较高,提高自动化配电网系统可靠性。

ABSTRACT ： In order to monitor the automatic balancing scheduling of power supply load, a data acquisition routing mechanism which can achieve the grouped data balancing in a single channel is put forward. Firstly, the queue length of node of grouped data in single channel is used as the decision parameter to establish the routing metric model. Sec- ondly, the minimum metric value is used as the decision condition to design data acquisition routing mechanism in single channel. Finally, the load balanced dispatching monitoring is realized through automatic adjustment of data sampling period of grouped data in single channel, the adjustment of data acquisition and input, and the output matc- hing ratio of grouped data reconstruction. Simulation results show that the proposed method can effectively improve the congestion of single channel data. The efficiency of data acquisition is high. The reliability of automatic distribution network is improved.
