Abstract

The invention relates to a coordinated boiler control method and system of a generating set. The method comprises that a target load set value, a load set value after speed limitation, a load down change speed set value and a load up change speed set value of the coordinated control system of the generating set are collected in real time; the load down change speed set value and the load up change speed set value are corrected according to the load set value after speed limitation and the load change state respectively to obtain a load down change speed correction value and a load up change speed correction value, and the load down change speed correction value and the load up change speed correction value replace the load down change speed set value and the load up change speed set value respectively; and according to the target load set value, the load set value after speed limitation, the load down change speed correction value and the load up change speed correction value, the coordinated control system of the generating set is controlled in real time in the coordinated manner. Thus, the load of the generating set is controlled smoothly, and safe operation of the generating set is ensured.

Description

technical field [0001] The invention relates to the technical fields of automatic control and thermal power engineering, in particular to a method and a system for coordinated control of generator sets, boilers and furnaces. Background technique [0002] Energy is an important material basis in the process of social development and an important driving force for economic development. At present, thermal power generation is still the main source of electricity. Therefore, improving the energy efficiency level of coal-fired generating units to achieve energy conservation and emission reduction has become a huge challenge for the power industry. [0003] Coal-fired generator set furnace coordination control system is one of the key control systems of coal-fired generator set. In the current coal-fired power unit's machine-furnace coordinated control system design, the unit's load change rate is a fixed value set manually. When the load changes, the load command transitions to ...
