A kind of active power distribution method of hydropower station agc based on unit combined output model

Abstract

The invention discloses a hydropower station AGC active allocation method based on a unit commitment output model. A unit AGC control module receives AGC active allocation values of a whole station and compares the values with an operation area given by a unit commitment output model module, an AGC allocation process is started to acquire a single unit AGC active allocation value input into each AGC unit, and the allocation value is issued to the unit. The method solves the problems of active power allocation, avoidance of a hydropower station unit vibration area (or prohibited operation area), compatibility of primary frequency modulation and the like, functional partitioning, parameter arrangement and strategy design are performed on automatic power generation active control of the hydropower station, and functional blocks form an organic whole through data exchange and strategy cooperation.

Description

technical field [0001] The invention belongs to the technical field of hydroelectric power generation control, and relates to an AGC active power distribution method of a hydropower station based on a unit combination output model. Background technique [0002] The control of active power output in hydropower stations generally adopts that the active power target value of the whole plant is first distributed to each hydro-generator unit (referred to as unit) through the automatic generation control function (Automatic Generation Control, referred to as AGC), and then each unit is passed through the computer respectively. The monitoring system uses a programmable logic controller (Programmable Logic Controller, referred to as PLC) or a speed governor to perform proportional integral derivative (abbreviated as PID) closed-loop adjustment. But so far there is no systematic algorithm that covers and guides all active power control links such as hydropower unit output modeling, s...
