In this article the construction of a high-frequency high-voltage commercial flyback transformer to supply an input voltage for a tesla transformer is proposed. The purpose of a demonstration is a breakdown through the air gap of electrode. To confirm the proposed method the design of control of a flyback converter by using a commercial flyback transformer is rated with a 10 to 15 kV output voltage to supply a tesla transformer at a rated 30 kV and 120 kHz. The experimental results of an output breakdown design of the electrode and the setting for a 1 cm space are constructed. The electrodes consisted of the following: sphere–sphere electrode plane–plane electrode sphere–plane electrode and rod–plane electrode. It was found that there was a breakdown at the output electrode in all cases. Accordingly there was a breakdown with a 2 cm sphere diameter with reference to the IEC 60052-2002 standard; after that it was compared with the standard table and the atmospheric and temperature at the laboratory were adjusted resulting to a high voltage equal to 31.5 kV.

The application of integrated energy use in the agriculture sector It is presented in the form of using renewable energy from solar energy to produce electricity to use in conjunction with other sources of electricity such as generators or electric power systems. Using solar panels or solar cells the size and number of panels does not exceed 300 watts 4 panels and the electrical system of the electrical system. Supply electric power to the water pump size does not exceed the rating of 1500 watts 220 volts. Solar power supply systems alone may be affected by weather conditions or electrical power supplies. Including the quality of electricity obtained from solar energy and will result in the water pump not working efficiently. Therefore the application of solar energy by using a power supply system from 2 sources by using a hybrid inverter device to select the power supply from the solar cell is the main power and the power supply from the memory system is the backup power. Therefore a research project on the application of solar water pumps in a mixed system for agriculture is proposed to increase the efficiency of electric power distribution. This application of solar water pump hybrid system for agriculture when used with water pumps can normally help to save electricity and can also use solar energy instead of using electricity to pump water. Let the water pump and can work efficiently.

The effects of load frequency control (LFC) of interconnected distribution power system in tie-line substation area load –frequency stability and the frequency respond at distribution generator (DG) are very important for interconnected control power system of tie-line area. The generating power system of solar farm and wind turbine which have interconnected distribution power system in tie-line substation area were tested using 3 simulation parameters: non-controller Automatic Voltage Regulator (AVR) and with Pl Controller. The results showed that there were 3 types of load and frequency changing in the interconnected area: load changed 0.02 p.u. had frequency of load changed 0.025 Hz and large disturbance. Comparisons of load-frequency to respond for steady state the time respond was 7.9 seconds for non-controller 5.4 seconds for AVR and 1.7 seconds for under controlled system at 0.1 p.u using Pl controller. Therefore the Pl controller has better efficiency than non-controller about 31 % and AVR about 16%. It can be concluded that the interconnected distribution power system in tie-line substation area controlling for storage for connected grid had better efficiency and optimization of generating power from renewable solar farm and wind turbine which have interconnected distribution power system in the nearby are balance of controlling of the original system.

This research aimed to study powe generation from heat loss strove by thermoelectric generator unit. As cooking with a gas stove can cause heat loss between the stove and the cookware this heat loss from gas stove can be converted into the electricity. For the experiment the researcher used a gas stove model KB5 installed with thermoelectric plate model TEG1-241-1.4-1.2 connected in a series to the power of 4 modules. Then experimental conditions of the gas pressure in the gas strove were set at 0.1 0.2 0.3 0.4 0.5 and 0.6 kg/cm2 respectively while the amount of mixed air was constant during the experiment. The results showed that when the gas pressure was at 0.6 kg2 the temperatures of the hot side and cold side of the thermoelectric generator was equal 250.5oC and 65.5oC respectively. Lt also generated the highest electric power of 53.3 watts. The power conversion efficiency was 5.3% at 38.1 Volts with 1.4 Amperes. In addition when electric was connected to a thermoelectric generator unit with 12 VDC 7-watt LED bulb the gas pressure in the gas stove were set at 0.3 0.4 0.5 and 0.6 kg/cm2 respectively was affected by the difference between the heating temperature and the cold temperature in the range of 185o C that could lighten up LED bulb.

This research study is the application of Geographic Information System (GIS) for distribution substation. The main purpose is to satisfy user by planning to support the increase of load at present and in the future. Moreover increase in creditability of distribution system by increasing new substation or expand the area of exist substation. Then Geographic Information System is necessary for the mentioned reason. Geographic Information System is the process of geographical data in computer system that defined useful information and related to spatial data such as residential property house number location latitude and longitude. Geographic Information System consists of capture store manipulate analyze manage and present all types of geographical data according to user’s objective. So Geographic Information System is the utility that be useful for distribution substation project. The research is planning to use Geographic Information System for finding Break-even point between increasing new substation or expand the area of exist substation which is 2 case studies.
