摘要： A sensor system for measuring an operating parameter of a wind turbine component is described. The fiber optic sensor system comprises a light source for outputting light in a predetermined range of wavelengths, and an optical fiber comprising a long Fiber Bragg Grating, extending continuously over a length of the optical fiber to provide a continuous measurement region in the optical fiber. The optical fiber is coupled to the wind turbine component such that the continuous measurement region is located at a region of the wind turbine component to be sensed, and such that the grating period at each location in the continuous measurement period is dependent upon the value of the operating parameter at that location. A light detector receives light from the optical fiber, and provides an output signal to the controller indicating the intensity of the received light; based on the detected light, a value for the operating parameter is determined.

摘要： Disclosed is a solution to automate a seal oil float trap by-pass for a hydrogen cooled generator. An automated by-pass system is coupled to an existing manual by-pass system for a float trap for a hydrogen cooled generator. The automated by-pass system includes at least one solenoid valve and a controller that controls opening and closing of the solenoid valve. The automated by-pass system can also include manual valves, orifices and limit switches. The controller activates the solenoid valve to allow the seal oil to drain. The controller can also provide a notification alarm that the hydrogen cooled generator is being purged.

摘要： An electric rotating machine comprises a rotor body of cylindrical structure and a stator body covering an outer peripheral portion of the rotor body in a non-contact fashion. The stator body includes a stator winding formed with an insulation layer and arranged radially outward of the rotor body with a clearance from the rotor body and a stator core which supports the stator winding. The electrostatic capacity of the stator winding is measured by an electrostatic capacity measuring instrument which comprises a housing having a size allowing the housing to be accommodated in the clearance between the rotor body and the stator winding, a support body detachably secured to the rotor body and adapted to support the housing within the clearance to be movable, and a measuring element mounted to the housing on the side of the housing facing the stator winding and adapted to measure electrostatic capacity of the stator winding, wherein a degree of water penetration into the insulation of the stator winding is determined based on a measurement data from the measuring element.

摘要： In a thermal overload protection system three system variables are sensed and provide the inputs required for a calculation conducted in real time at one second intervals. The system variables include ambient inlet air temperature to the alternator, alternator stator winding embedded sensor temperature, and traction motor armature current. A traction motor current limit is calculated using the inlet air temperature and the sensor temperature. The thermal overload is then controlled in response to the traction motor current.

摘要： Method and apparatus for cooling shaft seals of a turbine-generator system which includes a hydrogen inner-cooled generator having a stator with a cylindrical core and a rotor mounted for rotation on a shaft within the cylindrical core, a turbine coupled to the shaft at one end of the generator, an exciter coupled to the shaft at the other end of the generator, and a pair of seals each of which surround the shaft at both ends of the generator for substantially minimizing a leakage of hydrogen therefrom. Each of the seals includes a seal ring with a hydrogen side and an air side, and a closed loop oil supply is provided for each such side. One closed loop oil supply supplies oil to the hydrogen side of each of the seals, and another closed loop oil supply supplies oil to the air side of each of the seals, and both oil supplies are coupled within a heat exchanger for exchanging heat between the two closed loop oil supplies.

摘要： An apparatus for monitoring hydrogen leakage from a generator frame into the stator coil water cooling system. The monitor is designed to alert the operator should leakage exceed a rate of twenty cubic feet per day (20 cfd). A pressure relief valve set at four (4) psig and orifice are provided, along with a second relief valve having a higher setpoint than the first, such that pressure will increase in the holding tank if leakage exceeds 20 cfd setpoint of the orifice. A high pressure alarm, set at a level higher than the first relief valve but less than that of the second, will then sound to alert the operator to protect the system from an overly large or gross failure of the system. By continusouly monitoring a relatively small steady state leakage rate, the operator can be aware of a minor problem which can be corrected at a scheduled maintenance outage, before a gross failure of the system, requiring a costly shutdown of the turbine-generator, would otherwise occur.
摘要翻译：一种用于监测从发电机框架到定子线圈水冷却系统的氢气泄漏的装置。监视器旨在提醒操作者，泄漏超过每天二十立方英尺（20 cfd）的速率。提供设置在四（4）psig和孔口处的减压阀以及具有比第一安全阀高的设定点的第二安全阀，使得如果泄漏超过孔口的20ccd设定点，则保持罐中的压力将增加。然后，设置在高于第一安全阀但低于第二安全阀的水平的高压警报器将发出警告，以保护系统免受系统过大或大的故障。通过不断地监测相对较小的稳态泄漏率，操作人员可以意识到在计划的维护中断之前可以纠正的一个小问题，在系统出现故障之前，需要昂贵的关闭涡轮发电机，否则发生。
