Integrated energy saving system of power supply and distribution system

Abstract

The invention relates to an integrated energy saving system of a power supply and distribution system, wherein all energy saving devices and power quality control devices of the power supply and distribution system are integrated to form the integrated energy saving system which implements unified control to cause the power supply and distribution system to always run in the most economical manner; in every subsystem, all the energy saving devices are unified to work coordinately and cooperatively so that the distribution network can achieve the best energy saving effect. The integrated energy saving system structurally comprises a supervisory computer monitoring module, a communication module and a plurality of execution submodules; the supervisory computer monitoring module carries out visual and real-time control to the whole system and adopts a mass memory device and a large management database; the communication module adopts the Ethernet, a fieldbus and wireless communication device and other modules of the system for communication; the execution submodules comprise a comprehensive series-control energy saving device, a configuration monitoring device, a fieldbus device, a reactive power compensation device, a voltage stabilizing device, a harmonic wave regulating device, a frequency control device and an intelligent box-type substation device.

Description

Technical field: [0001] The invention relates to a comprehensive energy-saving system of a large electric power system, in particular to a comprehensive integrated energy-saving system of a power supply and distribution system. Background technique: [0002] At present, there is a huge waste of electric energy in the power supply system and power distribution system. In addition to the low technology of power saving devices, reactive power compensation devices, harmonic control devices and frequency converter devices on the market, the biggest problem is that they operate individually and cannot be coordinated. Working together, the overall energy-saving effect is very poor. For example, in the power supply system, the reactive power compensation device cannot work on demand, either under-compensation or over-compensation, which leads to active power loss of the transmission line, and a large amount of electric energy is wasted on the power line. On the road, reactive power ...

This mode results in a huge loss of electrical energy

[0003] The current power supply system and power distribution system operate independently, and the current management system does not manage the two systems together. Specifically, it does not unify and control all energy-saving devices, resulting in relatively poor energy-saving effects and reactive power flow. Harmonics run wild in the power grid at all levels, threatening the stable operation of the power system
