power plant intrinsically safe dc power system
the dc power supply system of the power plant is an important part of the secondary power system. it is the power supply for important equipment such as relay protection, safety automatic devices, and measurement and control systems. it is related to the operational safety of the entire substation, power plant and even related power grids. however, the key technical solutions and equipment of the power plant dc system have remained at the level of more than ten years ago, without major development and innovation. common grounding, insulation drop, ac intrusion, short circuit, ring network, battery failure and other faults, as well as fault line selection, still plague the operating staff of the substation, power plant dc power system, threatening the safe and stable operation of the entire power grid.
the power plant intrinsically safe dc power supply system solves the problems of dc system grounding, insulation drop, ac intrusion, short circuit, ring network, battery fault and other problems, as well as fault line selection and other issues, to ensure the safe operation of the plant dc power system.
