ABSTRACT:
The operation of a geothermal well power-generation system is monitored by sensor, communication, and performance monitoring equipment permanently associated with the operating power generation system. Sensors detect changes in well water temperature, in water pressure below and above the pump, and in pump rotating speed. This data is transmitted by multiplex communication to receiver and utilization means at the earth's surface. A novel permanent magnet generator system supplies the signal representative of pump rotation speed and also supplies electrical power for the multiplex communication of the sensor output signals.
