Intelligent power generation control and optimization system

Abstract

The invention discloses an intelligent power generation controlling and optimizing system, wherein a front-end processor realized by a telecontrol communication server is used for receiving instructions sent by a dispatching master station; a lower computer realized by a measuring and controlling device is used for collecting data of a unit; the inside of an upper computer is provided with background monitoring software; an evaluation index value of each unit is calculated by the background monitoring software; a unified control strategy is generated according to a target value instruction or a local setting planned value sent by the dispatching master station and received by the telecontrol communication server; a control instruction is sent to the units through a lower computer measuring and controlling device; the real-time control is performed on all the plant units according to different operation manners and operation conditions; a busbar voltage or a plant reactive power and an active power is automatically kept at a current given value; the front-end processor and the lower computer can be flexibly selected, so that the intelligent power generation controlling and optimizing system is good in expansibility, has an integration function of AVC (Automatic Voltage Control), AGC (Automatic Generation Control), optimization of operation, and can be used in heat-engine plants, hydraulic power plants, wind power plants, solar power plant, regional centralized control centers and the like.

Description

technical field [0001] The invention relates to an intelligent power generation control and optimization system, which belongs to the technical field of electric power dispatching automation. Background technique [0002] Power system automatic voltage control (AVC) and automatic generation control (AGC) are an integral part of power grid dispatching automation. Through AGC / AVC, real-time tracking and regulation of generator active power and reactive power output is carried out, and reactive power compensation equipment and main transformers in substations are monitored and controlled. The timely adjustment of taps can effectively control the reasonable flow of active and reactive power in the regional power grid, optimize the distribution of power flow in the power grid, effectively improve the voltage quality of the power grid, and improve the stability and economy of power grid operation. [0003] The disadvantages of existing power system technology are as follows: [0...

AI Technical Summary

Problems solved by technology

[0004] 1) Most of the products are implemented based on RTU (Remote Terminal Unit), with poor scalability

[0005] 2) The system design is not flexible and the function expansion is difficult

[0006] 3) Logic and locking are implemented by code, which is difficult to implement and debug on site

[0007] 4) Basically only has AVC function, lacks AGC function, does not have integrated function
