Study of Voltage Balancing Methods for Accumulator System of Substation

doi:10.11985/2016.12.007

Abstract

Abstract:

Accumulator system, which can be used as DC sources of power substations, is of great significance to the power supplying system. However, the imbalance of voltages between different batteries is a restraining factor to the overall performance of accumulator system. Three different kinds of voltage balancing methods are discussed in the article, based on which a novel balancing method with DC-DC converter is proposed, and then the practicability of the method is analyzed through simulation.

Key words: Accumulator, DC-DC converter, energy loss, voltage balance
