Abstract

The invention discloses an active power distribution network monitoring method, device and system, and the method comprises the steps: determining a monitoring time point according to a monitoring signal; collecting current data in a preset cycle and voltage data corresponding to the monitoring time point according to the monitoring time point; analyzing the current data and the voltage data in the preset cycle to obtain operation information; wherein the operation information represents the operation condition of the active power distribution network. The problem that real-time operation information and fault operation information of the active power distribution network are difficult to collect can be solved.

Description

technical field [0001] The present application relates to the technical field of distribution network, and in particular, to an active distribution network monitoring method, device and system. Background technique [0002] With a large number of distributed new energy sources connected to the distribution network, the traditional distribution network has changed from a passive network to an active network. However, due to the limited existing monitoring methods, the transient operation information of the active distribution network cannot be effectively captured, and the monitoring methods are lacking, which is not conducive to quantitative analysis of the impact on the distribution network after the access of distributed new energy sources, and it is also difficult to accurately Collect real-time operation information and fault operation information of active distribution network. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned technical problems...
