摘要

新型电力系统中，由于新能源发电占比不断攀升且其具有强烈的不确定性，抗扰动成了火电机组功率控制的核心任务。目前火电厂功率控制系统仍然采用PID控制，难以满足火电机组深度、连续、频繁调峰调频的需求。为了使先进控制理论更好地应用于火电机组功率控制，借力PID控制的工程基础实现了线性自抗扰控制（LADRC）的平滑应用。通过分析LADRC的结构以及反馈环的传递函数，得出了LADRC的PID实现形式，并通过Simulink仿真进行验证。仿真及工程应用测试表明，LADRC的PID实现继承了自抗扰控制突出的扰动抑制能力。在相同的PID及相关参数下，LADRC的PID实现对各类扰动都具有突出的抑制能力，其中三阶LADRC的扰动抑制能力最强、调节速度最快。LADRC的PID实现能够满足火电机组功率控制系统的需求，控制品质优于常规PID控制。LADRC的PID实现扩展了LADRC的工程应用空间。

Abstract

In the new power system

due to the constantly rising proportion of new energy generation and its own uncertainty

anti-disturbance has become the core task of power control of thermal power units. At present

the power control system of thermal power plants continues to use PID controllers

making it challenging to accommodate the needs for deep

continuous

and frequent peak shaving and frequency regulation in thermal power units. The advanced control theory has an outstanding contradiction between theoretical rigor and industrial practicability

in order to make it better applied in power control of thermal power units

the smooth application of linear active disturbance rejection control(LADRC) is realized by using the engineering basis of PID control. By analyzing the structure of LADRC and the transfer function of the feedback loop

the PID realization form of LADRC is defined and verified by Simulink simulation. The simulation and engineering application tests show that the PID implementation of LADRC inherits the outstanding disturbance rejection ability of ADRC. Under the same PID and related parameters

the PID implementation of LADRC shows outstanding suppression ability to all kinds of disturbance signals

and the third-order LADRC has the strongest disturbance rejection ability and the fastest adjustment speed. The PID implementation of LADRC can meet the requirements of power control system of thermal power units

and the control quality is better than that of conventional PID control. The PID implementation of LADRC expands the engineering application space of LADRC.
