Abstract

The invention relates to the technical field of automatic control, and discloses a method for analyzing influence of controller parameters on automatic power generation control regulation performance, which comprises the following steps: enabling a coordination control system to respond to an automatic power generation control instruction based on a coordination control structure of direct energy balance and the adjusted controller parameters; calculating the adjusting rate, the adjusting precision and the response time of a power loop in the process of responding to the automatic power generation control instruction; keeping the parameters of the main steam pressure loop feedback controller and the feedforward controller unchanged, so that the proportional gain and the integral gain in the power loop feedback controller are increased or decreased respectively, the same automatic power generation control instruction is responded, and the adjusting rate, the adjusting precision and the response time of the power loop when the proportional gain is increased or decreased are calculated respectively; and completing the influence of main steam pressure loop feedback and feedforward controller parameters on the adjustment rate, the adjustment precision and the response time. The method can analyze the influence of the controller parameters on the automatic power generation control regulation performance, and provides guidance for controller parameter optimization.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method for analyzing the influence of controller parameters on automatic power generation control and adjustment performance. Background technique [0002] In order to absorb large-scale new energy sources such as wind energy and photovoltaics, thermal power units need to quickly respond to automatic power generation control commands to absorb large-scale new energy. The adjustment performance of automatic generation control is used to evaluate the units participating in automatic generation control. The adjustment performance of automatic generation control mainly includes three indicators of adjustment speed, adjustment accuracy and response time, all of which have clear definitions and calculation methods. [0003] As an important control loop for thermal power units to participate in automatic power generation control regulation, the coordinated control system bas...
