OPTIMIZATION OF DEB COORDINATED CONTROL SYSTEM FOR 300 MW UNIT
摘要
阐述了DEB协调控制系统的原理和特点。针对某电厂300 MW机组协调控制系统设计的缺陷和不足
提出了详实的优化改造方案
并给出了参数整定的步骤。实际投运结果表明
改造后的协调控制系统既有良好的升降负荷适应能力
又能保证机组参数稳定。
Abstract
The principle and features of Direct Energy Balance (DEB) coordinated control system have been expounded. Directing against defects and inadquacy of the coordinated control system designed for 300 MW units in one power plant
a full and accurate optimized retrofit scheme has been put forward
and steps of parametric setting being given. Practical operation results show that the retrofitted coordinated control system has both good adaptability for load increase and load reduction
as well as ensuring the parameters of the units to be stabilized.
