Intelligent reactive power optimization control system and method

Abstract

The invention discloses an intelligent reactive power optimization control system and method. The system comprises a data acquisition module, an MCU module and a data transmission module which are connected in sequence, wherein the MCU module is connected with the switching control module, the environment monitoring module, the extended output module, the power supply module and the human-computerinterface module;the data transmission module is in wireless connection with the monitoring management cloud platform, and the monitoring management cloud platform is in wireless connection with theterminal. The method comprises the following steps: powering on the system and configuring parameters and peripherals; starting a communication serial port to receive data, and starting tasks such asinterruption of each timer; performing a data communication processing task with SVG reactive power compensation equipment; analyzing and storing the data; returning and uploading the corresponding data; and switching on and off capacitors according to judgment standards. According to the scheme, most of reactive power of the power load end is compensated by using the power capacitor, and then theremaining changed reactive power is compensated by using the SVG, so the compensation performance and the economic performance are combined, and the control balance of SVG and power capacitor combined switching is realized.

Description

technical field [0001] The invention relates to the field of power control, in particular to an intelligent reactive power optimization control system and method. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, various types of power equipment are used in industry, agriculture and residents' family life. According to data, most power electronic devices, such as TV sets and air conditioners, have relatively large inductive loads and low power factors, and the reactive power consumed occupies a large proportion of the electricity transmitted by the grid. The increase of reactive power causes the transmission current of the line to increase, resulting in increased line loss and equipment loss, resulting in a large amount of power loss. With the implementation of national energy-saving and consumption-reducing policies and the strengthening of environmental protection, reactive power c...
