直接能量平衡控制策略分析及在湛江电厂2号机组上的应用

Analysis of Direct Energy Balance Control Strategy and Its Application in Unit 2 of Zhanjiang Power Plant

针对湛江发电厂2号机组在进行混煤掺烧后,热工自动调节系统扰动大的情况,提出在机组的协调控制系统逻辑上引入直接能量平衡(DEB)法则的办法,为此,分析了在协调控制系统上引入直接能量平衡控制策略的优点,并介绍了直接能量平衡在湛江电厂2号机组实施的技术方案,从实验曲线来看,该方案取得了较好的效果。

When the undesigned coal was burnt in Unit 2 boiler of Zhanjiang Power Plant, destabilization of the automatic adjustment system was very big, As a result, it was proposed that direct energy balance （DEB） strategy be introduced into the logic of the coordinated control system. In this paper, the advantages of the introduction of DEB strategy are analyzed, and the concrete technology project is presented. The test results after the system modification show the good effects of the project.
