Problems solved by technology
During the operation of the steam turbine, the greater the acceleration, the greater the pressure the steam turbine needs to bear. Once the steam turbine is under too much pressure, it will easily lead to a loss of control

The invention provides a steam turbine speed regulation method and system and a storage medium. The steam turbine speed regulation method comprises the following steps that the actual rotating speed is monitored, specifically, steam turbine rotating speeds monitored at multiple points are received, and the actual rotating speed is obtained according to the rotating speeds monitored at the multiplepoints; rotating speed control is conducted, specifically, a steam turbine speed increasing rate and a target rotating speed are received, the actual rotating speed is increased to the target rotating speed according to the speed increasing rate, and the actual rotating speed is controlled to be the target rotating speed; overspeed protection is conducted, specifically, a rotating speed upper limit threshold value is received, whether the actual rotating speed is higher than the rotating speed upper limit threshold value is judged, and if yes, an alarm signal is sent. The rotating speed of the steam turbine is monitored in real time, and data acquisition timeliness is guaranteed; when the steam turbine is started, the steam turbine is controlled to stably and rapidly increase the rotatingspeed, the target rotating speed is set, the actual rotating speed is controlled to be the target rotating speed, and steam turbine operation stability is guaranteed; the rotating speed upper limit threshold value is set, when the actual rotating speed is monitored to exceed the rotating speed upper limit threshold value, the alarm signal is sent, and the problem that workers do not respond in time is solved.
Description
technical field [0001] The invention relates to the technical field of steam turbine control, in particular to a steam turbine speed regulation method, system and storage medium. Background technique [0002] The steam turbine is a rotary steam power device. The high-temperature and high-pressure steam drives the rotor equipped with blade rows to rotate, and at the same time, it does work externally. Steam turbines are the main equipment of modern thermal power plants, and are also used in metallurgical industry, chemical industry, and ship power plant. [0003] When a steam turbine starts running, it is usually necessary to set a target speed and a rate increase acceleration. During the speed-up process of the steam turbine, in order to improve work efficiency, we usually need to reach the target speed quickly and stably. During the operation of the steam turbine, the greater the acceleration, the greater the pressure the steam turbine needs to bear. Once the steam turbine...
