Gas turbine test bed power supply system providing power uninterruptedly

Abstract

The present invention discloses a gas turbine test bed power supply system providing power uninterruptedly. The system comprises a generator, dual-power supply switch devices, a rapid switch device, circuit breakers, a distribution box for the test bed, and an uninterruptible power supply (UPS). A power source generated by the generator and the UPS are rapidly switched by a first dual-power supply switch device and the rapid switch device and then are transferred to the distribution box for the test bed. A first circuit breaker is disposed between the UPS and the first dual-power supply switch device. An intelligent circuit breaker is connected between the generator and the first dual-power supply switch device. The first circuit breaker and the generator are in signal connection. When the UPS fails, a signal is transmitted to the generator, so as to control the generator to start automatically, and the intelligent circuit breaker turns on automatically so as to output power. When the UPS is on, the generator receives a signal and turns off automatically. The gas turbine test bed power supply system providing power uninterruptedly ensures that the test bed works constantly and reliably.

Description

technical field [0001] The invention relates to the technical field of gas turbines, in particular to a gas turbine test bench power supply system capable of uninterrupted power supply. Background technique [0002] A gas turbine is a rotary power machine that converts thermal energy into mechanical energy using continuously flowing gas as a working medium. In recent years, its related research and development work has received extensive attention from the National Development and Reform Commission and the Ministry of Science and Technology, and has been included in the key development areas of my country's long-term science and technology development plan. On the basis of the design and development of gas turbines, it is necessary to carry out experimental research for numerical verification and design optimization, which requires the construction of gas turbine test benches. [0003] The power supply system provides electricity for testing and general lighting for the gas...

Problems solved by technology

However, the high-power UPS is relatively expensive, the power supply time is limited, and the battery pack occupies a large area and has poor environmental performance.

[0005] Some systems also use dual power supplies, but with conventional power switching devices, the switching time between power supplies is generally greater than 300ms, and the slowest can reach 1 to 2s. During this time, the real continuous power supply has not been realized.

Moreover, some equipment in the dual power supply is shared. When the shared equipment fails, the gas turbine test bench will also face a power outage.
