Hydrogen control system for electric generator

A power generation system comprising:

• a turbine;
• a generator operatively connected to the turbine, the generator including a housing containing a gas mixture;
• a purity monitoring system (PMS) fluidly connected to the housing, the PMS monitoring a purity of hydrogen in the gas mixture;
• a mass flow control system fluidly connected to the housing, the mass flow control system being configured to measure a flow rate of a gas mixture extracted from the housing and modify the flow rate of the gas mixture across a range of flow rates;
• and
• a vent conduit fluidly connected to the mass flow control system, the vent conduit receiving a portion of the gas mixture from the mass flow control system and feeding the portion of the gas mixture to an outlet.

A combined cycle power generation system comprising:

• a gas turbine;
• a heat recovery steam generator (HRSG) operatively connected to the gas turbine;
• a steam turbine operatively connected to the HRSG;
• a generator operatively connected to at least one of the gas turbine or the steam turbine, the generator including a housing, the housing containing a gas mixture;
• a purity monitoring system (PMS) fluidly connected to the generator, the PMS monitoring a purity of hydrogen in the gas mixture;
• a mass flow control system fluidly connected to the housing, the mass flow control system being configured to measure a flow rate of a gas mixture extracted from the housing and modify the flow rate of the gas mixture across a range of flow rates;
• and
• a vent conduit fluidly connected to the mass flow control system, the vent conduit receiving a portion of the gas mixture from the mass flow control system and feeding the portion of the gas mixture to an outlet.
