This research study analyzes the problem of waste water from the burning of palm trees which are used as fuel for power generation of palm ash. It is used to ferment biogas as a fuel for power generation where a large amount of wastewater from the gas digester is completed. The wastewater is then pumped out of the gas digester. Biological in large quantities Therefore to study the analysis of wastewater to find a method for designing a wastewater treatment system from high voltage systems from the corona discharge principle when adding ozone it is necessary to analyze the chemical effects of the wastewater according to the standard values of the Department of Industrial Works.

This thesis presents an application of particle swarm optimization technique (PSO) to optimal economic dispatch analysis in power system with contingency criteria for management power system operation cost power loss and bus voltage. The objective of optimal economic dispatch for contingency in power system compared with the results of analysis power system in normal case. The study result show that when contingency occur in power system operation cost are rising. In the other hand system stability are decrease.

The propose of this research present a comparative study of the Reliability Improvement of Electrical System for Electric Mass Rapid Transit Train which describes in term of the power supply efficiency including voltage imbalance that could indicate how much the electric power quality is being more or less. The electrical system to be used in the Mass Rapid Transit system has 4 types of connection between three (3) phases of Metropolitan Electricity Authority (MEA) transformer and station transformer which is Single phase V-Type Scott and Le- Blanc to be considered for the different transformer connections type could be carried out and resulted in the most unbalanced in power supply as well as properly solution for power supply mitigation of voltage imbalance. From foregoing the data analyst was discovered that a single phase connection could cause the most unbalance voltage but on the other hand Le-Blanc connection is the least unbalance which could be reduced the impact on the Mass Transit Train and increase the credibility of consumers in order to continuity implement service usage.

การเพิ่มเสถียรภาพของระบบไฟฟ้ากำลังด้วยอุปกรณ์ FACTS

At present the electrical power system has growth and more complicate. Because of the development of the economics and society. An increasing the demand of power transmission line system would be resulted in the stability and reliability. The Flexible AC Transmission System devices: (FACTS) is the equipment which can control the flow of real power. In addition it can gladly encourage the stability and reliability of the power transmission line system. This research proposed the impact of placing power electronics device to increase stability and reliability of power system in order to study the impact of Flexible AC Transmission System devices: (FACTS) devices for the resulting to stability of power system. UPFC devices model which consisted of Static Synchronous Compensator and Static Synchronous Series Compensator that worked as independent voltage source for technique to proposed control the flow of real power and reactive power as well as voltage bus in power system. Testing Simulation power flow control of 5 buses by placing unified power flow control indicated the effective compensation of real power and reactive power in power system.

This project is intended as a teaching medium air conditioning system and simulation of air conditioning system problems. Some of them have been modified to suit their teaching needs. Arduino microcontrollers are used to control the system. By starting the study of the air conditioning system thoroughly. The microcontroller is written to control the operation of devices like the air conditioning system when the system malfunction. It will be used to analyze the problems of air conditioning. The experimental set will display the voltage and current. The connection points of the air conditioning problem analysis. When the symptoms are bad. The analyst can solve the problem by connecting or pressing the button of the device. The results of the project. The test will measure the difference of the air conditioning unit. And read the amount of current and volume in the system. To diagnose abnormalities and choose a solution to the problem from the kit system that can be displayed to solve the problem that the analyst was correct or not with the LED status light. Based on the performance test a demonstration kit for the demonstration of efficiency of the air conditioning system was provided to 10 experienced air conditioning technicians. 80s of issues. The reliability of the demonstration set and the efficiency of the simulator case study of the electrical system in air conditioning systems is acceptable
