Optimization design of BOP system for hydrogen energy storage power station with limited water resources ——Engineering analysis under full-load water supplementation and unverified heat source conditions
水资源受限氢储能电站BOP系统优化设计——满负荷补水与热源未验证条件下的工程分析

摘要

化德县电网侧储能示范项目可研按地下水作为生活、工业和消防补水水源，循环水补水按30 m3/h考虑，并配置50 t/h地下水处理系统，但可研同时注明水文地质报告和水资源论证尚未落实。项目实施后，井水实际产量不足20 t/d，满负荷补充冷却水为10至15 t/h，单一地下水源无法满足连续运行。可研中的循环水设计流量为1700 m3/h，供回水温度为32℃和42℃，设计温差10℃；现场记录的冷却塔进出口温差为20至30℃，需按同一回路和稳定工况复核。本文对可研假设与现场数据进行对照，提出分项计量、多水源补给、雨水及燃料电池排水回用、储水降载和首冬热源试验要求。

Abstract

The feasibility study for the Huade County grid-side energy storage demonstration project uses groundwater as the water source for domestic, industrial, and fire-fighting purposes, with a circulating water supply capacity of 30 m3/h and a 50 t/h groundwater treatment system. However, the feasibility study also notes that the hydrogeological report and water resource assessment have not yet been completed. After project implementation, the actual well water production is less than 20 t/d, and the full-load cooling water supplementation is 10 to 15 t/h, which cannot meet the continuous operation requirements of a single groundwater source. The design flow rate of circulating water in the feasibility study is 1700 m3/h, and the supply and return water temperatures are 32℃ and 42℃, with a design temperature difference of 10℃. The on-site recorded temperature difference between the inlet and outlet of the cooling tower is 20 to 30℃, which needs to be verified under the same circuit and stable operating conditions. This paper compares the feasibility study assumptions with field data and proposes requirements for component metering, multi-source water supply, rainwater and fuel cell drainage reuse, water storage load reduction, and the first winter heat source test.
