Abstract

The invention is applied to the technical field of electric energy quality treatment, and provides a remote and online monitoring system for a static var generator, which comprises a data collector, a data server and a client, wherein the data collector is used for being connected with the static var generator SVG, collecting data of the SVG and updating the SVG data to the data server via a wireless network; the data server is used for receiving the SVG data updated by the data collector and analyzing the data and storing the data to a local database; and the client is used for reading corresponding data in the database of the data server according to an operation instruction, and carrying out corresponding operation on the read data. Through the system of the invention, a worker can monitor operation states of each SVG and the system in real time through operating on the client without arriving at the SVG operation site, powerful data resource supports are provided for SVG site debugging, operation performance evaluation and fault analysis, and early warning is provided for possible fault through data analysis.

Description

technical field [0001] The invention belongs to the technical field of power quality control, in particular to a remote on-line monitoring system for a static var generator. Background technique [0002] With the rapid development of modern society, the demand for electric energy is constantly increasing. At the same time, the large-scale use of rectifier equipment in electrical equipment, the emergence of impact loads, unbalanced loads, and large loads have caused the quality of power grid power supply to decline, and power quality problems are becoming more and more serious. Arouse the attention of the power supply side and the power consumption side. The static var generator (Static Var Generator, SVG) is an active dynamic var compensation system with the core of the power electronic device IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor) that can be turned off. , Smoothly and accurately provide capacitive and inductive reactive power, thereby ...
