摘要： 为满足煤炭行业和煤矿企业对于供电可靠性日益增长的需求,同时探索兆瓦级储能系统在工业用户侧的实用化解决方案,本项目在内蒙古乌海平沟煤矿设计建造了基于铅酸电池和磷酸铁锂电池储能技术的矿用兆瓦级智能应急电源。系统主要功能为：在电网正常供电时,替代传统的油浸电容器进行无功补偿;在电网出现供电故障时,为煤矿的特别重要负荷提供至少30 min的连续可靠供电。除此外,系统还可根据用户需求执行包括削峰填谷、分布式新能源发电波动平抑在内的多种功能。为保证应急电源系统的安全性、可靠性和使用寿命,本工作在进行设计时着重考虑了蓄电池的选型、容量配比、成组设计以及储能变流系统（PCS）的电路拓扑设计和电池维护高级智能控制策略,旨在探索和实用。

Abstract: In order to meet increasing safety demands from coal industry and mining company, a lead acid and lithium iron phosphate (LFP) based battery energy storage is developed for a megawatt level emergency power supply in Pinggou coal mine of Wuhai, Inner Mongolia. If the local power grid works normally, the proposed system compensate the reactive power instead of the use of traditional static capacitor. When there is a local grid failure, the energy storage system provides stable power to extremely critical loads of coal mine for at least 30 min. Besides, the proposed energy storage system could also play a role in the ‘peak shaving’ and smoothing distributed energy generation for the demand side. To ensure safety, reliability and sufficient lifetime, the work is focused on the selection of batteries, capacity ratio of different batteries, circuit topology and smart control strategy design of the power conversion system.

Key words: energy storage system, power conversion system, battery, coal mine grid
