Example Embodiment

[0029] Hereinafter, preferred embodiments of the present invention are given in conjunction with the accompanying drawings to illustrate the technical solutions of the present invention in detail, but the present invention is not limited to the scope of the described embodiments.

[0030] In the present invention, the thermal power generating set includes an APS system and an MCS system, and the MCS system includes multiple MCS sub-circuits.

[0031] In order to realize the seamless connection between the APS system and the MCS system, the present invention provides an automatic control method for thermal power generating units. Specifically, it provides a parallel management strategy for realizing the entire APS process and full range of automatic start and stop of thermal power units. The "closed-loop full-process automatic at any time" design scheme, that is, in the APS step sequence design and the MCS interface design, any MCS sub-loop can be put into automatic at any time to ac...

Abstract

The invention discloses an automatic control method of a thermal power generator plant. A parallel management strategy of automatic startup and shutdown of a thermal generator plant APS in the whole process and the whole range and a design scheme that a closed-loop is automatic at any time in the whole course are provided. The method comprises steps that when an MCS sub-loop should be invested and also is qualified for automatic investment, an APS system is automatically invested into the MCS sub-loop via an APS step order instruction; when the MCS sub-loop should be invested but is not qualified for the automatic investment, the APS system carries out APS setting opening or carries out forced opening by protecting overriding condition; and the APS carries out automatic setting on an enclosed loop set value in each of the MCS sub-loops according to states of the thermal generator plant. The objectives of the invention are to achieve parallel control of automatic startup and shutdown of the thermal generator plant APS in the whole process and the whole range; shorten control period; reduce effects on the control process imposed by change of working conditions; and provide technical precondition for obtaining of higher control quality of one-click start of the plant.

Description

Technical field [0001] The present invention relates to the technical field of thermal power process control of a thermal power generating set, in particular to a parallel-based thermal power generating set APS (unit automatic start-stop control system) management strategy and a design scheme for the entire interface between APS and MCS (analog control system) The control method of the thermal power generating set. Background technique [0002] The APS system realizes the whole process automatic control from the unit start preparation to full load and from the full load reduction to zero until the unit completely stops. The execution process of the APS system pays attention to the adjustment process and the stability of the system process, which is extremely important for parameter and state control. The instability of any control loop parameters will affect the control of the APS system. While increasing the adjustment time, it also prolongs the execution time of the APS system...
