<p>A novel testing system and method for the MW-level wind driven generator set is presented. The electric power fed by the network is supplied to a drag motor with double extended shaft by a series of devices. The drag motor drives the generator set to be tested by a series of devices, including a wind wheel simulator. The power generated by the generator set to be tested is fed back to a distribution transformer by a series of devices. The energy feedback is achieved then. The generator set to be tested can simulate the wind driven generator characteristic on different wind power using the wind wheel simulator. The output characteristic of the generator set to be tested can be detected by the measurement system. In the same time, the low voltage ride through capability of the generator set can be tested by setting a LVRT device on the power feedback link. The invention has such advantages as that, energy can be saved, the system configuration is flexible and the power range is wide, the controlling performance and the output power feature of the generator set can be tested, the low voltage ride through capability of the generator set can be tested by the LVRT device, the testing system has strong compatibility and expandability, the test condition on the spot can be known in a timely manner so as to satisfy the multilateral test demands.</p> |
