燃煤机组网源互动可调出力在线监测模型研究与应用

为避免特高压故障对受端电网的冲击，及时、有效地提升本地发电资源的快速、动态响应能力，开展了基于网源协调理念的燃煤机组可调出力在线监测模型研究，主要从机组供热、主要辅机运行状态、煤质变化3个方面实时评估受端电网主力燃煤机组的可调发电出力裕量，为电力调度部门在应对特高压故障时提供决策参考意见。该模型目前已在江苏电网投入试运行，动态评估全省130余台主力燃煤机组的动态可调出力，为电力调度运行人员提供实时、可靠的在线监测评估结果。

Research and Application of Online Monitoring Model of Coal-Fired Units in the Coordinated Interaction of Large Power Grid

To avoid the impact of UHV faults on the receiving end power grid and effectively enhance the response ability of the local power resources, the study on the adjustable output online monitoring model is carried out based on the concept of power grid coordination. The model assesses the adjustable power output margin of the main coal-fired units in the aspects of the heating unit, the main auxiliary equipment running state, and the coal quality. This model tends to help the electric power dispatching department for decision making on dealing with extra high voltage failures. The model has been put into trial operation in Jiangsu power grid and been dynamically evaluating the adjustable output of more than 130 units in the province, providing real-time and reliable online monitoring and evaluation results.
