Abstract

The invention discloses an SVG-based multi-level coordinated energy-saving optimization control system for a distribution network, which includes a hardware acquisition control layer, a communication data integration layer, a software application layer and a configuration display layer. Through the combination of software and hardware, it is beneficial to improve the comprehensive energy-saving control of the distribution network, combine power quality and energy conservation, and establish a monitoring, analysis, decision-making, governance, and evaluation through control, acquisition units, controllable equipment, communication, and advanced software analysis applications. Integrated system; effective control of harmonic pollution, optimization of three-phase unbalance and compensation of reactive power. The present invention combines the advantages of capacitive reactive power compensation energy-saving equipment, SVG static var generator and active power filter APF, effectively realizes the control of harmonic pollution, optimizes three-phase imbalance and compensates reactive power; the present invention The combination of flexible reactive power adjustment equipment SVG and APF is adopted, with flexible power output, accurate compensation capability and fast response.

Description

technical field [0001] The invention relates to a multi-level coordinated energy-saving optimization control system, in particular to an SVG-based multi-level coordinated energy-saving optimization control system for a distribution network, which belongs to the field of intelligent control. Background technique [0002] According to the survey data, although my country's power industry has made progress in energy conservation and consumption reduction, compared with the world's major industrial countries, the coal consumption of power supply is still about 50 grams / kWh behind the world's advanced level. That is to say, calculated according to the world's advanced level, my country currently consumes about 100 million tons of standard coal for power generation a year. The line loss rate is 2% to 2.5% higher than that of most developed countries, which is equivalent to 45 billion kWh of electricity loss per year, which is roughly equivalent to the annual electricity consumptio...
