百万级超超临界火电机组新型协调控制策略分析
摘要：目前,国内超超临界火电机组普遍存在AGC模式下电负荷响应速率不足的问题,主要原因是协调控制系统的主汽压力调节品质差。由于主汽压力控制存在多变量相互耦合的因素,如何消除各变量互耦作用就成为提高主汽压力调节品质的核心技术。通过理论分析提出一种新型协调控制策略,将协调控制系统变负荷公用指令进行分解,形成多个彼此独立的子系统变负荷前馈量,并设计一套智能型防燃料超调逻辑,成功地达到了解耦目的。该控制策略应用到中电投安徽平圩三期2×1050MW超超临界火电机组,并取得良好的应用效果,实践证明该策略能够改善主汽压力调节品质,进而提高电负荷响应速率。
Abstract:At present, the domestic ultra-supercritical thermal power unit AGC mode are widespread the problem of insufficient electricity load response rate,the main reason is that the poor quality of coordinated control system of main steam pressure control. Due to the main steam pressure control of multivariable coupling factors are variables how to eliminate the mutual coupling effect becomes the core technology to improve quality of main steam pressure control. The author through the theoretical analysis, a new coordinated control strategy is proposed to load change public instruction in decomposition of coordinated control system, to form multiple independent subsystems variable load feedforward quantity, and design a set of intelligent fuel overshoot logic, successfully achieve decoupling. The control strategy is applied to the CLP vote for anhui pingwei three periods of 2×1050MW ultra supercritical thermal power unit,and achieved good application effect, practice shows that this strategy can improve the quality of main steam pressure control, electric load response rate can be improved.
