考虑实时调度的电力系统配电网远程自动监控方法

Remote Automatic Monitoring Method of Power System Distribution Network Considering Real-time Dispatch

利用目前方法对电力系统配电网远程自动监控研究时,存在监测故障次数与实际故障次数差距大、时间长、漏报率和误差率大的问题,为此提出考虑实时调度的电力系统配电网远程自动监控方法,通过构建实时调度模型对电力系统配电网进行分析,并确立电力系统的约束形式,分析完成后对电力系统中的配电网进行故障监测,从中获取最大小波奇异值,根据最大小波奇异值对配电网线路状况的反映,完成对电力系统配电网的远程监测。实验结果表明方法的精准度较高、实用性较强。

When using the current method to study the remote automatic monitoring of power system distribution network,there are some problems,such as large gap between the number of monitoring faults and the actual number of faults,long time,large missing re-port rate and error rate.Therefore,a remote automatic monitoring method of power system distribution network considering re-al-time dispatching is proposed,and the power system distribution network is analyzed by constructing a real-time dispatching model.The constraint form of the power system is established.After the analysis,the fault of the distribution network in the pow-er system is monitored to obtain the maximum wavelet singular value.According to the reflection of the maximum wavelet singu-lar value on the line condition of the distribution network,the remote monitoring of the distribution network of the power system is completed.The experimental results show that the proposed method has high accuracy and practicability.
