Development of Fast Power Control System for New Energy Farms
With the continuous improvement of new energy penetration rate,it is difficult to ensure the frequency stability only by relying on conventional thermal power units.Power administrations generally cannot clearly know the frequency modulation performance of new energy farms owing to their nature of pursuing economic benefits.This threatens security of power system.In order to solve the problem of insufficient frequency support of conventional thermal power units and the difficulty of monitoring the frequency modulation performance of new energy farms in real time,this paper studies the key technologies such as online monitoring system,frequency measurement,asynchronous sampling,and control strate-gy,and develops a new energy fast power control system.Third party testing has verified the high performance of this scheme.
