Abstract

The invention relates to the technical field of cold start of steam turbines, in particular to a cold start early warning system and method of a steam turbine, a storage medium and electronic equipment. The problems that a system adopted by an existing steam turbine in the prior art is low in intelligence and differentiation degree and has no targeted early warning method and measure are solved. The system comprises a parameter acquisition module for acquiring real-time parameters in the cold start process of the steam turbine, a database module for storing a simulation parameter threshold value, a similar unit parameter threshold value and an operation requirement parameter threshold value, and a judgment module for comparing the real-time parameters with three parameter threshold valuesof the database module at the same time and outputting comparison results, a warning module for giving an alarm to prompt normal or abnormal conditions according to the comparison result, and a suggestion module for suggesting parameter setting when abnormal conditions are prompted. The system is used for parameter monitoring and setting suggestions in the cold start process of the steam turbine,and the effects of shortening the cold start time of the steam turbine and being more intelligent and differentiated are achieved.

Description

technical field [0001] The invention relates to the technical field of cold start of steam turbines, in particular to an early warning system, method, storage medium and electronic equipment for cold start of steam turbines. Background technique [0002] With the rapid development of my country's power industry, intelligent control technology has been gradually applied to the start-up, operation and maintenance of power plant equipment. As the main equipment of modern thermal power plants, steam turbine is a rotary steam power device that converts steam heat energy into mechanical work. When the steam turbine has been shut down for a period of time and reaches the ambient temperature, it is called a cold start when it is started again. At this time, it is necessary to make various preparations before the cold start before it can be started normally. [0003] During the cold start process of the steam turbine, whether it is the start of the medium pressure cylinder or the jo...
