The invention also discloses a method for remotely monitoring the power grid by utilizing the reactive power compensation device, and a large number of acquisition points of the power grid can be remotely monitored and the communication costs are reduced by the system and the method for remotely monitoring the power grid by utilizing the reactive power compensation device.

Description

technical field [0001] The invention relates to the technical field of electric power system and communication, and more specifically, relates to a system and method for remotely monitoring a power grid with a reactive power compensation device. Background technique [0002] In the power system, according to statistics, the current reactive power loss of typical domestic urban and rural power grids is roughly as follows: divided by voltage level, 0.4kV level loss accounts for about 50% of the total loss, 10kV level accounts for about 20%, and 35kV level accounts for about 20%. . In rural power grids, long-distance power supply is more common, and 10kV line losses are relatively large; in urban power grids, the reactive power loss of large industries is at the 10kV level, while others are generally at the 0.4kV level. Therefore, it is of great significance to do a good job in the reactive power compensation of the power grid below the 10kV voltage level. However, the 10kV l...
