Test system and method for regional stability control system

The invention provides a test system and method for a regional stability control system, the test system comprises a test host, a plurality of test sub-machines and a plurality of communication interface devices, the test sub-machines are connected with stability control sub-machines, and one stability control sub-machine corresponds to one test sub-machine. A communication interface device is arranged in each of the stability control main station and each stability control sub-station, and the test host and the test sub-machine are connected through the communication interface devices. The test method specifically comprises the following steps: establishing communication between the test host and the test sub-machine, selecting test content and formulating corresponding test data, forwarding the test data to the stability control sub-machine through the test sub-machine, adjusting the running state by the stability control sub-machine, determining a stability control strategy and a corresponding control comm
