  • 가스터빈을 이용하는 발전시스템 중에서 발전용량이 300kW 이하인 시스템을 마이크로터빈 발전 시스템이라 하며, 가스터빈에서 배출되는 폐열을 활용하여 열효율을 극대화시킨 것이 열병합발전 시스템이다. 마이크로터빈 열병합발전 시스템은 소형이면서 발전 및 열효율이 높고, 환경친화적인 제품 특성을 갖고 있으며, 또한 기존에 주로 사용되고 있는 천연가스 및 액체연료 뿐만 아니라 유정이나 쓰레기 매립장 등에서 버려지는 낮은 품질의 가스도 연료로 사용할 수 있도록 하여 에너지 활용도를 높일 수 있다. 본문에서는 국내에서 개발중인 65kW급 마이크로터빈 열병합발전 시스템을 소개하고 현재까지의 개발현황을 정리하였다.

  • Cogeneration systems are seen as a significant innovation for dispersed energy generation since they are both environmentally friendly and has comparatively high degrees of efficiency. It is especially suited for the decentralized provision of electricity and heat. However, it causes operational problems such as voltage regulation, voltage variation, protection and safety. Especially, it is expected that the interconnection/disconnection operation of cogeneration system has an effect on distribution voltage regulation and variation. Recently, with the increased use of customer-owned computers and other sensitive electronic equipment, electric power quality has become an important concerns. Therefore, the voltage quality problems with cogeneration system should be investigated because the voltage quality is an important part of electrical power quality. In this paper, the momentary voltage dips associated with the interconnection/disconnection operation of cogeneration system are analyzed, including restraint solutions at the customer level. In addition, the unit capacity of cogeneration systems per feeder are evaluated from the view point of momentary voltage variations. The results of this paper are useful analysis data for interconnection standards/guidelines of cogeneration systems and dispersed generation (DG)

  • The distribution of the combined heat and power system is active as a solution to the instability of energy supply and environmental pollution caused by continuous industrial development. In Korea, the safety standards for combined heat and power system using a gas engine are insufficient therefore the study on this is needed. In this study, the safety performance and structural/material assessment items of domestic and international standards applied to the combined heat and power system were analyzed to carry out a standardization study on safety performance applicable to 20 kW gas engine combined heat and power system. In addition, the safety performance assessment (plan) of the gas engine combined heat and power system was derived by performing risk analysis and risk assessment using HAZOP. Assessment items include engine ignition systems related to safety performance, piping tight performance, watering and temperature rise performance, combustion performance, electrical efficiency, thermal efficiency, overall efficiency and humidity performance. Gas and water pipes, gas control and shut-off valves, durability, heat resistance, and cold resistance of metal or non-metallic materials related to the structure and materials of the gas engine combined heat and power systems.

  • 열병합발전시스템의 경제성은 배열을 회수하여 사용함으로써 전기를 생산함과 동시에 열을 사용하여 에너지의 효율을 높이는데 있다. 그렇지만 열과 전기의 사용이 동시에 이루어지지 않을 경우에는 열병합발전시스템의 장점이 사라지게 된다. 이 논문에서는 열병합발전시스템의 효율을 계산하는 방법을 제시하여 열병합발전시스템을 도입하는 단계에서 좀 더 체계적인 방법으로 분석할 수 있는 방법을 제시하였다.
