Embodiment Construction

[0040] An inertial power coordinated control method applicable to a thermoelectrically coupled solar cogeneration system of the present invention will be described in detail below with reference to embodiments and drawings.

[0041] The present invention is an inertial power coordination control strategy applicable to thermoelectric coupling solar energy cogeneration systems. In order to deal with the problem that the dynamic response of the power supply equipment of the solar energy cogeneration system is not The power lacking in power generation is added to the command of the gas turbine through the inertial link, and the power of the solar thermal power generation system and the gas turbine power generation system during operation is redistributed, and the fast response characteristics of the gas turbine are used to reduce the load shortage, thereby speeding up the response of the system. Improve the dynamic adjustment process of the system; at the same time, use the bufferi...

Abstract

The invention discloses an inertia power coordination control system suitable for cogeneration of thermoelectric coupling solar energy. The inertia power coordination control system comprises the following stages: (1) establishing a solar thermal power generation subsystem model; (2) establishing a gas turbine subsystem model; (3) establishing a waste heat boiler and steam turbine mathematical model; (4) analyzing a thermoelectric conversion mathematical relationship of the solar combined heat and power generation system; (5) adding an inertia power compensation link; and (6) optimizing the time constant by applying a grey wolf algorithm, and improving the system performance, so that the method is suitable for a comprehensive energy system for grid-connected power generation of various devices, and the problem of system performance reduction caused by the response speed problem can be improved.

Description

technical field [0001] The invention relates to a similar thermoelectric coupling solar cogeneration system, in particular to an inertial power coordination control system suitable for thermoelectric coupling solar cogeneration. Background technique [0002] As the main driving force of all walks of life in today's society, fossil energy plays a vital role in the development of society. In the power industry, the consumption of fossil energy such as coal, oil, and natural gas continues to accelerate, but due to its limitations, the storage capacity gradually decreases, which cannot meet the growing supply needs and does not meet the requirements of the scientific development concept; at the same time, coal, oil, and natural gas Excessive consumption of fossil energy such as fossil energy produces more carbon dioxide than the environment itself purifies, leading to the greenhouse effect, and incomplete combustion of coal and oil also produces toxic pollutant gases (such as ni...
