## 1 Introduction  
The Antarctic plateau is now widely regarded as offering the best atmospheric conditions for a ground-based astronomical observatory [1]. The Amundsen-Scott South Pole station's astronomical science activities have obtained a series of achievements. It found that the infrared sky emission was lower than typically found at mid-latitude sites in 1-2 orders of magnitude [1; 2; 3; 4] and the atmosphere held extremely low precipitable water vapor [5]. The expectation of weak free-atmosphere turbulence was also confirmed. A very strong turbulent surface layer, 200-300 m thick [6], was found, resulting in mediocre ground level seeing [7]. The cognition of astronomical observation conditions was moved forward by the Italian and French Concordia \"Dome C\" station. The local topography of \"Dome C\" indicated that the surface wind speed should be lower and thus, the turbulent boundary layer should be confined closer to the surface [5; 7]. These expectations have been confirmed by a series of site testing experiments operated over the last several years. The submillimeter opacity and infrared atmospheric emission was shown to be lower than observed at the South Pole [8; 9], and while the wintertime surface boundary layer was also found to exhibit relatively strong turbulence, this was confined to within 30 m of the surface [10; 11; 9]. The \"Dome A\" region has the Antarctic highest altitude of 4093 m [12] with thin air, minimum wind speed [13], and the least air layer disturbance [14; 15]. \"Dome A\" scientific activities started in 2008, which have gained some progress [16; 17]. Continuing to develop further astronomical science activities is significant. China National Observatory and Nanjing Astronomical Optical Instrument Research Institute manufactured an astronomical instrument called AST3 and sent it to work at \"Dome A\" from 2012, which has already made contributions to scientific research [18; 19; 20; 21]. The support of electricity supply and scientific instruments' thermal insulation is needed in the continuous observation activities under extreme environment conditions on \"Dome A\" with unattended equipment. AAOISE was employed to fit the demands of electric power and thermal energy, which AST3 used as logistic support equipment. AAOISE was designed and constructed during 2009-2010 at the Southeast University with the Purple Mountain Observatory, then, was delivered, installed, and commissioned at \"Dome A\" as part of the Polar Research Institute of China (PRIC) 2010 expedition. In early 2011, the AAOISE operated in Kunlun Station successfully. In 2019, the current AAOISE was perfected further and worked in Taishan Station fluently. Some small electrical energy generation systems have operated successfully in Antarctic, such as the PLATO designed by the University of New South Wales (Australia) [22]. Japan constructed a Syowa Base small-scale energy network (Syowa Base Micro-Grid: SBMG) through photovoltaics and wind power generation [23]. Research team from Taiyuan University of Technology implemented the design of a polar wind and solar hybrid power supply controller in Zhongshan Station [24; 25]. The AAOISE's power generation is similar to PLATO's power generation [22] but has obvious differences in its control strategy consideration. AAOISE consists of two banks of three single-cylinder diesel engines equipped with alternators. Each alternator offers 1.8 kwh of power. A new strategy is adopted to control power generation and transmission, which is called the ControlNet field bus technology. It has already had lots of application bases in the industry field. In this way, the master controller PLCs are core equipment of the control network and other equipment, including sensors and input modules, are cooperated with PLCs. All above jointly constitute the unified control network, ControlNet field bus. Not only are all the diesels and generators managed and set by the ControlNet field bus but also all the power supply and protection of the electrical equipment are.
