Real time monitoring of generator operation state based on convolution neural network

In order to monitor the transient stability of all generating units in power system，an improved convolutional neural network framework is proposed which can identify the real time operation status of generating sets online.The proposed framework uses the measured values obtained by the phasor measurement unit as the data source，and uses the convolution neural network with prediction pooling layer to realize the multi label classification function，so as to achieve the purpose of identifying a variety of generator operating states.The simulation test is carried out on IEEE 118 test system simulating various fault states.The results show that the proposed framework can quickly and accurately identify the operating state of the generator set，which is a feasible method to realize the on-line monitoring of the operating state of the generator set.
