Remote real-time monitoring system for reactive power of power grid user

Abstract

The invention relates to a remote real-time monitoring system for a reactive power of a power grid user. A local area network is internally connected platform application management server, a database server and a company internal management client side; the local area network is externally connected with a door as well as a client server and a data acquisition server; the door as well as the client server and the data acquisition server is externally connected on an internet through a fireproof wall; the internet is connected with an acquirer through enterprise optical fiber or a gateway GPRS supporting node; a reactive compensating device and an electric energy meter are connected on the acquirer. The system provides intelligent management to reactive power monitoring of a wide range of power grid users, is convenient to monitor and manage according to needs, so that the monitoring and managing effects are improved, and the maintenance cost is reduced.

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...
