Once there is an operation problem, it will lead to the reduction of smooth power supply, poor quality, and even affect the production and life of society, damage to the benefits of the power plant. Based on this, the author studies and discusses the centralized control operation of steam turbine, analyzes the existing shortcomings, and puts forward relevant operation optimization measures, in order to lay a solid foundation for improving the power generation quality and production efficiency of power plant.展开更多
