Abstract

Megawatt power impact frequently occurs during operation of industrial devices, which shows the features of high amplitude and strong randomness. Cascaded static synchronous compensator with battery energy storage system (STATCOMBESS) is a promising approach to solve the power impact problem. Cascaded STATCOM-BESS has advantages of large single-machine capacity and rapid response, however, which is not yet mature for industrial application. Aiming at this issue, study on cascaded STATCOM-BESS is conducted in this paper, comprising the parameters calculation and selection for cascaded static synchronous compensator (STATCOM), boundary capacity analysis and battery module number determination for battery energy storage system (BESS). Finally, the simulation results based on PSCAD/EMTDC validate effectiveness and correctness of the analysis and design for crucial parameters of STATCOMBESS, which can provide high-amplitude impulse active (1.5MW) and reactive power (2MVar) simultaneously after operation of STATCOM-BESS at 0.5s.

级联储能STATCOM用于脉冲功率补偿的研究

工业设备在运行过程中经常发生兆瓦级功率冲击，具有振幅大、随机性强的特点。级联式电池储能静态同步补偿器(STATCOMBESS)是解决电力冲击问题的一种很有前途的方法。级联STATCOM-BESS具有单机容量大、响应速度快的优点，但在工业应用方面还不成熟。针对这一问题，本文进行了级联式STATCOM-BESS的研究，包括级联式静态同步补偿器(STATCOM)的参数计算与选择、电池储能系统(BESS)的边界容量分析和电池模块数确定。最后，基于PSCAD/EMTDC的仿真结果验证了statcomess关键参数分析与设计的有效性和正确性，statcomess运行0.5s后可同时提供高振幅有功功率(1.5MW)和无功功率(2MVar)。
