Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0030] 1. Use the CAN bus to connect the power quality monitoring device installed at the distributed power generation system and the grid-connected point of the microgrid to the power dispatching center, and use the GPS time synchronization function of the monitoring device to make it timed and send power quality monitoring to the dispatching center at the same time data results, such as figure 1 shown.
[0031] The power quality monitoring device is a very mature power measuring device, and there are many types of products, which can be selected according to the monitoring purpose during specific implementation, and will not be listed in the present invention.
[0032] 2, figure 2 A flow chart of the method of the invention is given. In step 201, the dispatch center identifies abnormal data after receiving the data from the monitoring dev...
