Problems solved by technology

[0007] Due to the long period of APS design and debugging, a big problem in practical applications is that APS often overlaps and is inconsistent with other control functions and operation interfaces.
On the other hand, in the configuration realization method, the special algorithm module in the DCS system is mostly chosen. [3] To build, the APS function design must adapt to the existing functions of these algorithms, and power plant operators are often at a loss for such a redundant and complicated APS operation interface

Abstract

The invention discloses an implementation method of an operation interface of an automatic plant start-up &and shut-down system in a thermal power plant. Due to the common logic, control breakpoint and step sequence logic of the automatic plant start-up &and shut-down system provided by the method as well as the operation interface of the automatic plant start-up &and shut-down system and a modulating control system, the man-machine interactive design of the automatic plant start-up &and shut-down system is simplified, and the applicability of the automatic plant start-up &and shut-down system is improved. In addition, optimal control of a control outputting setting value of the modulating control system can be realized by adopting multiple goal constraint.

Description

technical field [0001] The invention relates to a design method of a thermal control system, in particular to a method for realizing an operation interface of a thermal power plant unit unit automatic start-stop control system. Background technique [0002] The Automatic Plant Start-up&Shut-down System (APS for short) of thermal power plant units is the highest level of control function in the unit automatic control system. In the 1980s and 1990s, some thermal power generating sets imported from Japan were designed with APS function. Due to the constraints of many factors such as the infrastructure commissioning cycle of domestic power plants, unit operation management mode, controllability and reliability of main and auxiliary machines, and the overall automation level of the unit, this function has not been able to be obtained in large-scale thermal power generation units designed in China so far. Promote apps. [0003] With the continuous improvement of the parameters a...
