AI Technical Summary

Technical Problem

Existing boiler systems struggle to effectively adjust main steam pressure deviations under complex operating conditions, impacting boiler operating efficiency and safety, and causing delays in load change adjustments.

Method used

By employing a signal acquisition module, a differential control module, a pressure deviation adjustment loop, and a command dynamic compensation loop, combined with a load and coal quantity function optimization module, the system generates precise coal quantity adjustment signals through real-time monitoring and analysis of the main steam pressure, load changes, and valve action signals of the boiler system, thereby achieving fine control of the boiler system.

Benefits of technology

It improves the boiler's operating efficiency and safety, reduces efficiency fluctuations and fuel waste caused by too much or too little coal, ensures more stable system operation, and optimizes the combustion process.

Abstract

Provided in the present disclosure are a boiler master control system, a pressure regulation method, an electronic device and a storage medium. The system comprises: a signal collection module, a derivative control module, a pressure deviation regulation loop, and a command dynamic compensation loop. Compared with the related art, in the embodiments of the present disclosure, a load change signal, a control valve actuation signal and a main steam pressure signal are used to compute a derivative action intensity, so as to precisely generate a first coal feed adjustment signal. This enables a timely response to load changes and pressure fluctuations, and thus ensures that coal feed adjustment is more precise, thereby avoiding boiler efficiency fluctuations or fuel waste caused by an excessive or insufficient coal feed; the pressure deviation regulation loop performs adjustment on the basis of the deviation of the main steam pressure signal, thereby further improving the stability of coal feed control; and the command dynamic compensation loop can effectively predict and adjust the coal feed on the basis of a dynamic change in a boiler load, a unit thermal energy storage parameter and a boiler capacity input rate, thereby adapting to dynamic changes in the boiler load and capacity.
