The invention discloses a control system for curing forming of a bent portion of a stator coil of a large-capacity air-cooled generator. The control system for curing forming of the bent portion of the stator coil of the large-capacity air-cooled generator comprises a master station control system, a heating and curing temperature control driving system, a temperature control system, a heater line breakage detection system, an industrial monitoring system and a mechanical electrical substation. According to the control system for curing forming of the bent portion of the stator coil of the large-capacity air-cooled generator, a master station controller is adopted, all control is automatically completed through the master station controller, manual intervention is not needed, control over heating, curing forming is achieved fully automatically, the labor is liberated greatly; temperature compensation is achieved by each temperature sensor through a standard thermal resistance temperature compensation instrument, and the accuracy of the temperature is improved; due to the fact each sensor is in zero-distance contract with the coil, heating precision is improved; the side which a heating plate coil leans against is integrally flat through full-screw-thread fit; on the whole, the quality of the coil is improved; due to the fact that the closed-loop PID algorithm is adopted, the temperature control precision can be improved, overshoot can be reduced, and the curing quality of the coil is improved remarkably.

The invention discloses a wind turbine generator fault maintenance method based on a structured knowledge base. The method comprises the following steps that S01, the structural knowledge base of windturbine generator faults is established, and the running data of the wind turbine generator is collected in real time; S02, when the fault occurs on the wind turbine generator, effectiveness discrimination is performed on the fault information, and when the fault is effective, S03 is entered; and S03, the running data, the fault information and the fault wind turbine set position information aretransmitted into the structured knowledge base, and a fault treatment scheme is obtained by matching. The invention further discloses a fault maintenance system which comprises a first module, a second module and a third module, wherein the first module is used for acquiring the running data of the wind turbine generator; the second module is used for carrying out effectiveness discrimination on the fault information when the wind turbine generator breaks down; and the third module is used for transmitting the running data, the fault information and the fault wind turbine set position information into the preset structured knowledge base when the fault is effective, and the fault treatment scheme is obtained by matching. The method and the system have the advantages of standardization in maintenance, high efficiency and the like.
