AI Technical Summary
Technical Problem
[0004]本实用新型旨在至少解决现有技术或相关技术中存在的技术问题之一，即固体储热系统无法快速且精准变负荷的问题
Benefits of technology
[0018]本申请的装置通过并联的多个固体储热器，且根据火电系统的具体情况确定每个固体储热器的储热量。当需要降负荷时，根据需要下降的量依次开启所需的固体储热器，使热量被存储，机组负荷下降；当需要升负荷时，根据需要上升的量反序依次开启已储热的固体储热器，使热量被释放，机组负荷上升。因此，本装置可以使火电系统在快速变负荷的同时，还能对负荷变化量进行精确控制。

Abstract
The application belongs to the technical field of solid heat storage and specifically relates to a solid heat storage device for variable load of a thermal power system. The device comprises multiple solid heat storages in parallel. The load reduction inlet end of each solid heat storage is connected to the heat source end of a unit in an on-off manner. The load reduction outlet end of each solid heat storage is connected to the temperature reduction recovery end of the unit in an on-off manner. The load increase inlet end of each solid heat storage is connected to the to-be-heated end of the unit in an on-off manner. The load increase outlet end of each solid heat storage is connected to the temperature increase recovery end of the unit in an on-off manner. The device can make the thermal power system control the load variation accurately while rapidly changing the load by the multiple solid heat storages in parallel and the heat storage capacity of each solid heat storage determined according to the specific conditions of the thermal power system.
