【Abstract】 A device for power system load recorder developed by the authors was introduced, which records load data according to criterion that we set. The facility is of some merit, such as easy to debug and shorten developing span. Practice proves that it can fulfill our expectation. The paper also depicts problems encountered in development. With the increasing of importance of power load modeling in power system analysis, this kind of device will be of wide future in practice.更多还原
