Abstract

DC power system of the nuclear power plant is used to supply DC loads for engineered safety featured instrumentation and control such as inverter, power system control and indication, and station annunciation [1]. Batteries of DC power system of the nuclear power plant uses lead-acid batteries in present, but new secondary batteries would be installed in nuclear power plant. This paper compares capacity design of lead-acid battery bank and super capacitor battery hybrid energy storage bank, when the battery was connected directly in parallel with the super capacitor. In addition, duty cycle diagram of class 1E DC power system and characteristic of super capacitor battery hybrid energy storage device are analyzed.
