印度TALWANDI电厂3×660MW机组协调控制策略及其实践

Coordinate Control Method and the Practice of India TALWANDI 3×660 MW Unit

通过对印度TALWANDI电厂3×660MW机组协调控制策略的设计和实践,分析了该协调控制策略的特点和优、缺点。采用这种双偏差(负荷、主汽压)控制回路策略,高质量地完成了合同中规定的2台机组负荷变动试验,机组变负荷过程平稳,主要控制参数指标如负荷、主汽压和变负荷速率均能满足合同中的技术标准。

Through the design and practice of coordinate control strategy（CCS） of 3 × 660 MW Unit of TALWANDI power plant in India, the characteristics, advantages and disadvantages of the CCS are analyzed. Adopt the double deviation（load and the main steam pressure）control loop strategy, the load change tests of the units specified in the contract are accomplished with high quality.Unit load changing process is stable, the main control parameters such as load, the main steam pressure and load change rate can meet all the technical standards of the contract.
