Flywheel-generating set based inertia simulation system

The invention relates to a flywheel-generating set based inertia simulation system. The system comprises a frequency converter, a prime motor, a flywheel group, a synchronous generator and excitationdevice and a mechanical connection part. The system can simulate the operation inertial of a multi-axle railway vehicle; and the problems including too large land occupation of a ground pit due to large and dispersed flywheel sheets, difficulty in axle base adjustment due to too large load during axle base adjustment and difficulty in inertial adjustment due to scattered installation of flywheel cases of different axles during railway vehicle inertia simulation of a railway vehicle rolling and vibration testing stand are solved; and brake test is independent from traction test in the testing stand, and the control difficulty of a traction converter is reduced needless of controlling the capacity of a dragging motor and the locomotive traction converter. 本发明涉及种基于飞轮-发电机组惯量模拟系统，该系统包括变频器、原动机、飞轮组、同步发电机及励磁装置、机械联接部件，本发明的
