Description

technical field

[0001] The invention relates to a remote real-time monitoring system for reactive power of distribution network users, and belongs to the technical field of distribution network monitoring. Background technique

[0002] In addition to substations in my country's distribution network, there is no special reactive power measuring device installed on the line, and the operating status of each line and the main transformer is unknown. Therefore, monitoring the operating status of the main lines and transformers in the distribution network is crucial to changing the Network operation mode, balanced line load, optimal line flow, prolonging the service life of equipment, have a very important impact on equipment life cycle management and other issues. For the reactive power monitoring of distribution network users, there is a lack of necessary means and measures, which affects the use of electricity by distribution network users and increases the maintenance costs of...
