| Abstract |
To supply natural gas, a system that uses the energy generated when high-pressure natural gas is decompressed to low pressure, that is, a turbo expander generator (TEG), is installed in the system to utilize new energy. In the past, the energy generated by decompressing natural gas in the supply management station was thrown into the air, but by using this to generate electricity, high-quality new energy that does not emit greenhouse gases and consumes fuel is obtained.
Accordingly, a significant portion of the existing decompression energy can be recovered, and the efficiency is very high in energy efficiency measures. This paper examines the characteristics of TEG power generation, examines the TEG pilot project and demonstration project conducted by Korea Gas Corporation, and discusses the voltage control scheme and grid interconnection |
