Vocabulary 5Electric Power Systems 1. 电力系统 power system automation Electric power systems refer to the components that transform other types of energy into electrical energy and transmit this energy to a consumer. Modern power systems all have the same basic characteristics: (1) are comprised of three-phase AC systems operating essentially at constant voltage. (2) use synchronous machines for generation of electricity. (3) transmit power over significant distances to consumers spread over a wide area.
