Rapid performance diagnosis device for concentrating solar power station

Abstract

The invention provides a rapid performance diagnosis device for a concentrating solar power station. The rapid performance diagnosis device has the advantages of high precision, automation, portability and flexibility in arrangement, and can rapidly diagnose the performance change of the concentrating solar power station so as to judge whether the concentrating solar power station works in a normal state or not, to ensure quick and accurate response of the power station and to ensure the normal operation of using equipment connected with the power station. The rapid performance diagnosis device comprises a physical measurement part, a data acquisition and transmission part, a performance calculation module and a diagnosis and output part. The data acquisition and transmission part comprises a data acquisition part and a data transmission part. The physical measurement part is used for measuring various physical quantities corresponding to operation of the power station. Data obtained by the physical measurement part is transmitted to the data acquisition part, and the data transmission part transmits the obtained data to the performance calculation module. The performance calculation module is used for programming an efficiency calculation model of the concentrating solar power station by utilizing a computer program.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a rapid performance diagnosis device for a concentrating solar power station. Background technique [0002] Concentrating solar power station, also referred to as photothermal power station or CSP power station, is a kind of optical device that uses optical devices to gather solar radiation energy, projects it into the heat collecting pipe, heats the working medium in the pipe, and uses the working medium to transfer heat to heat the circulating water to generate steam that drives the steam turbine. , The steam engine drives the generator to generate electricity. [0003] The current concentrating solar power plant is divided into solar concentrating heat collection system, energy storage system and steam power generation system. Its operating state in a complete working day is that when the sun rises to reach the concentrating condition, the concentrating heat col...

Problems solved by technology

[0004] The input energy of the concentrating solar power plant is solar energy, and the output energy is electric energy. The efficiency of converting solar energy into electric energy reflects the performance of the concentrating solar power plant. The existing technology cannot directly judge its performance during the operation of the concentrating solar power plant. Whether the work is normal can only be judged by whether the accumulated electric energy is normal. This judgment often lags behind, affecting the rapid response of the entire power station and affecting the normal operation of the equipment used in the power station.
