Voltage reactive power optimization energy-saving system of street lamp power supply network

Abstract

The invention discloses a voltage reactive power optimization energy-saving system of a street lamp power supply network, and belongs to the technical field of energy conservation of a street lamp power supply system. The system is composed of a voltage reactive optimization energy-saving system main station, a voltage reactive optimization energy-saving device and a communication network system. Based on the voltage reactive power optimization energy-saving system of the street lamp power supply network, voltage, power factors and other parameters of the power supply network are intelligently detected, a GPRS communication network is adopted, a host control system with four remote processing functions is formed, time-phased power supply voltage control of a street lamp is achieved, on the basis that illuminance and brightness of the street lamp are guaranteed, voltage reactive optimization of the power supply network of the street lamp is achieved, the energy-saving effect of the street lamp is achieved, meanwhile line loss and transformer loss are reduced, a lighting lamp is effectively protected, comprehensive analysis for economical operation of the power supply system of the street lamp is achieved, auxiliary decision-making bases are provided for sustainable development of city street lamp building, and fine management requirements for the street lamp are met.

Description

technical field [0001] The invention relates to an energy-saving system for optimizing the voltage and reactive power of a street lamp power supply network, which belongs to the technical field of energy-saving of municipal power supply systems. Background technique [0002] The street lamp control system is an essential functional part of the street lamp lighting system, but it has not received due attention from the very beginning. After years of development, the street lamp control system has only developed from the initial manual switch to the current relay timing switch, and a large number of manual fault inspections are still required. In recent years, the energy consumption of street lamps has attracted the attention of relevant departments, and the street lamp control system has also made great progress, moving towards the direction of intelligence, systematization and automation. [0003] With the continuous improvement and improvement of the urban road lighting p...

Problems solved by technology

[0004] At this stage, most of the street lamp management systems adopt the control mode of "time relay + AC contactor". The daily switch is timed. When the season changes, the parameters of each time relay need to be manually adjusted. At the same time, most street lamp control systems do not have real-time management. and background software or terminal equipment for adjustment functions

Therefore, most of the existing street lamp control systems can only control the timing switch of street lamps, which is inconvenient to adjust and the statistics of street lamp information are confusing.

[0005] To sum up, the existing street lamp control system has inherent deficiencies such as insufficient functionality and a low degree of automation, which can no longer meet the needs of intelligent lighting, energy saving and emission reduction in the new century.
