摘要

电力辅助服务市场下，燃煤火电机组参与调频辅助服务面临新的机遇和挑战。针对大容量超（超）临界燃煤火电机组锅炉蓄能有限和AGC调频响应性能较难适应辅助服务市场日益增长的调频需求，通过分析网源不同的能量状态对机组调频影响，设计了基于网源能量状态的自适应调频控制策略。该策略基于机组锅炉蓄能状态和电网调频需求，自适应地承担调频辅助服务市场中的AGC调频任务，充分发挥机组调频潜力的同时，有益于机组自身能量快速平衡和参数恢复平稳，实现机组安全稳定运行和提高机组综合调频性能指标的网源目标协同。

Abstract

In electric power ancillary service market

coal-fired thermal power units are facing new opportunities and challenges in participating in frequency regulation auxiliary services. During operation of large-capacity(ultra) supercritical coal-fired unit boilers

the energy storage is limited and the AGC frequency regulation response performance are difficult to adapt to the increasing frequency regulation demand of the ancillary service market. To solve these problems

the influence of different energy states of grid and source on frequency regulation is analyzed

and a self-adaptive frequency regulation control strategy based on grid-source operation state is designed. This strategy is based on the boiler energy storage state and the grid frequency regulation demand

and can adaptively undertake the AGC frequency regulation task in the frequency regulation ancillary service market. It fully exerts the frequency regulation potential of the unit

and is beneficial to fast energy balance and parameter recovery stability of the unit itself

which realizes the grid-source goal coordination of the safe and stable operation of the unit and the improvement of the comprehensive frequency regulation performance index of the unit.
