    Abstract: A hydrogen cooled generator includes a lubricant drain system. The lubricant drain system includes a hydrogen detraining tank having a hollow interior portion. A sensor is operatively mounted in the hydrogen detraining tank. The sensor is configured and disposed to detect an interface zone between an amount of lubricant and an amount of hydrogen gas in the hollow interior portion. A drain line is fluidly coupled to the hydrogen detraining tank. The drain line includes a first end portion that is exposed in the hollow interior portion and a second end portion. A valve is mounted in the drain line. A controller is operatively connected to the sensor and the valve. The controller is configured to selectively open the valve allowing a portion of the amount of lubricant to flow from the hollow interior portion when the interface zone is above the first end portion of the drain line.

    Abstract: A casing 102 surrounds a rotor 104, encloses a volume of a cooling gas 103 and has plural static seals. An end housing 120 at each end of the casing includes a seal system 121 through which the rotor 104 extends and cooling gas 103 escapes from the casing 102 to at least one seal area 123. A cooling gas regulator 110 and a gas source 108 maintain constant pressure in the casing. A scavenging system 130 removes a gas mixture 132 from each end housing 120 including escaping cooling gas 103. A leak detector 170 generates an alarm indicating a leak at one of the static seals in response to an increase in the cooling gas flow in the regulator and/or an increase in gas flow in the scavenging system. A seal alignment detector 172 generates an alarm in response to the seal oil flow rate, a difference between the temperature of the oil drain and inlet, and a seal oil filter 136 differential pressure. A seal clearance increase detector 176 generates an alarm in response to a ratio of time for which a scavenge control valve 134 operates to remove gas at a higher and at a lower scavenge rate

    Abstract: A hydrogen control system for a generator housing includes: a mass flow control system 100 fluidly connected to the generator housing, to measure a flow rate of a gas mixture extracted from the generator housing and modify the flow rate across a range of flow rates; and a vent 108 conduit fluidly connected to the mass flow control system, which receives a portion of the gas mixture from the mass flow control system and feeds it to an outlet. The generator can be operatively connected to a turbine 208, such as a steam turbine of a heat recovery steam generator, and a gas turbine (figs 4,5). The gas flow control system may include a mass flow control valve (fig 1, 110) and adjust the gas mixture flow rate base on a signal received form a purity monitoring system (PMS) 204 which can monitor environmental conditions within the housing, including hydrogen purity. Should the mass flow valve fail it can be closed and bypassed by opening a solenoid valve (fig 1, 112). The flow meter can be a thermal dissipation or a coriolis type. PMS 204 can transmit signals to an external database for diagnosis, efficiency and control analysis and to hydrogen source 106 to provide clean hydrogen to the generator. PMS 204 can include two independent analysers (fig 3, 304) connected to front, central and rear sections of the generator housing.

    Abstract: A system for diagnosing a seal oil system comprises: sensors 22A, for measuring a seal oil pressure differential across shaft seal 16; sensors 24A, 26A, for measuring a seal oil temperature differential across the seal; a sensor 34A,34B for measuring a hydrogen side seal oil flow rate ; and a systein for analysing data collected from at least two of the sensors in order to diagnose the seal oil system. The system can be used in a hydrogen cooled generator 10 having a shaft 14 with turbine end 30 and collector end 32, to diagnose shaft seals 16 about the shaft at respective ends and can include respective seal oil pressure differential sensors 22A, 22B and seal oil temperature differential sensors 24A, 26A measuring across both shaft seals 16. Sensor 34A,B can be located in a drain of a detraining tank 20. The system can identify potential failures and analyse using a computer (fig 2, 40) and a look-up table (fig 3).

    Abstract: A system for controlling a temperature of a generator 102 comprises a coolant fluid supply in fluid communication with the generator 102 and a heat exchange apparatus (e.g. plate and frame apparatus) 112,114 in fluid communication with the coolant fluid supply 106, the generator and a heat exchanger cooling fluid source 116. The system also includes a first sensor module 122 configured to determine a first temperature (Tin) of a fluid flowing from the heat exchange apparatus to the generator, a second sensor module124 configured to determine a second temperature (Tout) of the fluid flowing from the generator to the fluid supply 106 and a controller 120 configured to continuously determine, at a selected frequency, an operating limit temperature (Tlimit) for the fluid based on the determined first and second temperatures. Additionally the sensor modules may include sensors for measuring conductivity and pressure. Reaching the operational limit causes the generator to trip, an alarm sounding at, for example, five degrees below the limit temperature. The alarm may also be triggered by the conductivity measurements. In fig 2, Tboil and Kbulk are constants relating to the boiling point of the coolant and the properties of the generator stator windings.
