Research of Operation Modes of Reserve Power Supply

Taking distribution network ’two supply lines and two branches’as example,the paper analyzed existing problems and its advantages and disadvantage of probable modes and reserve modes in running,and put forward corresponding improvement measures and several methods about reserve power source automatic connection.It should be defined reasonable and reserve power supply modes by the information sharing,operation and reserve has priority in stair loads,give attention to integrated control measures for the healthy and stable of the system and quickly restore power supply of load classification in batches.It can improve reliability and success ratios of reserve power.
