SVG-based multi-level coordination energy-saving optimization control system for distribution network

Abstract

The invention discloses an SVG-based multi-level coordination energy-saving optimization control system for a distribution network. The system comprises a hardware acquisition control layer, a communication data integration layer, a software application layer and a configuration display layer. On the basis of hardware and software combination, integrated energy-saving control of the distribution network is improved; and the electric energy quality and energy conservation are combined. An integrated system with combination of monitoring, analyzing, decision making, treatment, and evaluation is established based on controlling, acquisition unit and controllable equipment arrangement, communication, and high-level software analysis application. Harmonic pollution treatment is realized effectively; and the three-phase unbalance and reactive power compensation are optimized. According to the invention, on the basis of combination of advantages of capacitor reactive compensation energy-saving equipment, an SVG static reactive power generator and an active power filter (APF), harmonic pollution treatment is realized effectively and the three-phase unbalance and reactive power compensation are optimized. With the way of combination of the flexible reactive adjusting equipment SVG and the APF, the flexible power output is realized, the compensation capability is precise, and the response speed is fast.

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...
