High Altitude Electromagnetic Pulse (HEMP) is a challenging agent aimed to destroy the most critical types of electronic equipment in the most important components of national infrastructure. The article addresses the issue of improvement of a power plant’s direct current auxiliary power systems (DCAPS) survivability under HEMP impact, and suggests certain simple measures and affordable technical means that ensure significant improvement of DCAPS’s resistance to HEMP.

In order to reduce loader engine installed power and save energy, we designed the driving scheme of power system for parallel hybrid loader by Analysis of different way of connection between diesel engine and electric motor. We chose ISG power electric multifunction and super capacitor as the core component to design the Loader auxiliary power system and movable arm cylinder gravitational potential energy recovery system. We established ADVISOR software model of hybrid power Loader, and the simulation results show that diesel engine installed power of the hybrid power Loader is reduced by 21%; fuel consumption is reduced by 9.2%. Through optimize control strategy, the diesel engine can always working in high efficient area or idle area. Practical application shows that this design scheme has the potential economic and environmental benefits.

AbstrakPertumbuhan industri di Indonesia tidak dipungkiri semakin lama, semakin meningkat secara signifikan. Mesin konverter merupakan mesin yang telah banyak digunakan di berbagai industri maupun pabrik di Indonesia. Pada dasarnya mesin konverter menggunakan energi listik yaitu arus searah DC dan arus bolakbalik AC. Tujuan dalam penelitian ini adalah untuk mengembangkan mesin konveter dengan menggunakansistem tenaga hybrid dan solar cell. Tenaga Hybrid umumnya merupakan penggunaan dua atau lebih suatu pembangkit listrik dengan sumber energi yang berbeda-beda. Rangkaian konverter ini mampu memperbaiki sistem distribusi kelistrikan untuk mengontrol tegangan beban untuk beban listrik statis maupun dinamis.Kata Kunci: konverter, sistem tenaga hybrid,solar cellAbstractThe growth of industries in Indonesia are not denied the longer, the more increased significantly. Converter is a machine the machine has been widely used in various industries as well as factories in Indonesia. Basically the engine use the energy converter listik are DC direct current and AC alternating current. Research purpose to develop a konveter machine using hybrid power system and solar cell. Hybrid power generally is the use of two or more of a power plant with different energy sources. The series of this converter is able to repair the electrical distribution system to control the voltage to load a dynamic or static electricity.Keywords: converter, hybrid power system, solar cell
