Abstract

The invention discloses an accuracy detecting method for a BCS system, and the method selects k heliostats to perform the following operations for each heliostat to determine the accuracy of the BCS system: sequentially forming m differently sized reflective mirrors on the mirrors of the heliostats such that the sunlight is reflected by the reflective mirrors to the BCS whiteboard to form spots; respectively obtaining the center coordinates of each spot; selecting the center coordinates of the corresponding spot when the area of the spectacle mirrors is the smallest as the center coordinates of a reference spot of the corresponding heliostat; respectively calculating the distances between the center coordinates of all the spots and the center coordinates of the reference spot of the corresponding heliostat; sorting the distances between the center coordinates of all the spots and the center coordinates of the reference spot of the corresponding heliostat in ascending order to obtain asample sequence S(D1, D2 to Dn); and determining i such that Di is the accuracy of the BCS system. The accuracy detecting method provided by the invention evaluates the accuracy of the BCS system by statistically analyzing the distance distribution of the centers of the spots deviating from the center of the reference spot.

Description

technical field [0001] The present application relates to the technical field of solar thermal power generation, in particular to a BCS system accuracy detection method and device. Background technique [0002] In the field of energy, solar energy is being used more and more as a clean and renewable energy source. In the field of solar power generation, there are two types of solar power generation: photovoltaic power generation and thermal power generation. With the development of science and technology, especially the rise of computer control technology, solar thermal power generation technology is a new solar energy utilization technology after photovoltaic power generation technology. Solar thermal power generation uses a large number of reflectors to gather the energy of direct sunlight in a focused manner, heat the working fluid, generate high-temperature and high-pressure steam, and use the steam to drive a steam turbine to generate electricity. [0003] Tower-type s...
