HIL을 이용한 증기터빈 발전기 시뮬레이터 개발에 관한 연구

Abstract

Steam turbine that is run using stream among industry plant, power plant or facilities of vessel is selected the usage in electricity generating mainly. This steam turbine generator？s composition department is consisted of steam turbine, generator and governor. It is difficult of search and expensive equipments are bulk.

Can consult together driving of turbine and generator to cyber by embodying from engine of this high price to simulator. Like this, can control or confirm the function even if do not combine governor physically in steam turbine development stage by doing.

Developed device is ideal that connect and test at the surrounding environment division directly but a lot of times, research expenses and risk bearing are required to equip the surrounding environment. So, do test for device using simulator. Can improve efficiency of examination composing this test environment by HILS.

In this paper, embodied simulator including this steam turbine and generator by HILS. Heighten space utilization and composed as industry PC of a PC 104 bus that hardly be influenced in surroundings environment.

Coded by C code modeling steam turbine and generator. Through D/A board of simulator, appeared speed of revolution signal goes by digital governor through V/F converter. Compare input value with speed command in digital governor. So, send signal that control displacement of actuator at A/D board of simulator. Can confirm speed signal and actuator displacement signal that become input and output of simulator by real-time.

Confirmed whether simulator displays idle speed and rated speed command of digital governor properly, and confirmed whether output of simulator changes along the raise?low rate of the speed. Confirmed effectiveness of steam turbine simulator that design and manufactures using HILS from result of above.
