System and method for providing ballast loading for a turbo-generator
First Claim
1. A method of providing controlled turbine loading in a turbo-generator based cooling system, comprising the steps of:
- monitoring an output voltage of the turbo-generator;
selectively coupling a ballast load to an electrical output of the turbo-generator to maintain the output voltage at a predetermined level.

Abstract
A ballast load control system and method is presented that regulates the output electrical power supplied by a turbo-generator such that appropriate turbine loading may be achieved. Such enables the use of a turbo-generator having an expansion turbine to be used to provide a controlled, required amount of cooling to a thermal control system. By effectively varying the coupled electrical load, the loading provided to the expansion turbine may be controlled while maintaining output power requirements to connected electrical utilization equipment. Use of a common system controller for both the cooling system and ballast trim load system of the present invention ensures coordinated operation between the required amount of cooling and electrical power quality supplied to the coupled utilization equipment.

12. A ballast load system for use with a turbo-generator having a gas driven turbine drivably coupled to an electric generator, the electric generator producing an electrical output upon operation of the turbine, comprising:
-
a ballast load module;
a control module having an input for receiving the electrical output of the generator, and an output coupled to the ballast load module; and
a system controller having a first sensory input to sense the electrical output of the generator, the system controller commanding the control module to selectively couple the ballast load module to the input thereby varying an electrical load connected to the generator to maintain the electrical output of the generator at a predetermined level. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
