Description

technical field [0001] The invention belongs to the field of closed cycle power generation technology / turbine power generation technology, and specifically relates to a power generation performance test system of a high-speed generator used in a closed cycle power generation system. Background technique [0002] The closed-cycle power generation system is a special turbine power generation technology in which the working medium repeatedly participates in cycle power generation. It only exchanges energy with the outside world without material exchange, so it can be applied in special environmental conditions such as deep space and deep sea without air. It is a small turbine power development new direction. [0003] In the closed-cycle power generation system, the high-temperature working medium at the front end of the turbine engine drives the turbine to do work, converting heat energy into mechanical energy, and then the turbine drives the generator connected to the rear end...

Problems solved by technology

[0005] High-speed motors have the advantages of high power density and high efficiency, but they face great difficulties in testing the power generation performance of the motor. The traditional test method is to test the motor on the drag test bench. The test scheme is as follows: figure 2 shown

This test method has high requirements on the motor-to-drag test bench, and there are technical problems such as extremely high coaxiality requirements in the connection and measurement between the tested motor and the towed motor, and most of this test scheme can only test the tested motor. Linear power generation performance cannot cover the full working range of the motor, let alone verify the performance when it works in conjunction with drive equipment such as generator controllers, and the component test coverage is incomplete
