This thesis presents the Power Quality (PQ) analysis of solar power plant 1MW and economic impacts in the distribution power networks. The case study focuses on the penalty fee (fine) from consume the reactive power less than the limit of the Provincial Electricity Authority (PEA) of Thailand. The fine have been charged up to 900000 baht per year. Therefore the thesis studies and purposes the possible solution by analysing the operating function of the inverter (supports reactive mode) installing the adjustable capacitor bank 1500kVar in the Medium Voltage (MV) level and lastly installing the adjustable capacitor bank 1500kVar in the Low Voltage (LV) level. The results shown that the possible solution that reduces the fine is installed the adjustable capacitor bank 1500kVar in the MV. The investment of this installation is cost 1800000 baht with the nominal operation over 10 years. The analysis of financial investment which bases on the Net Present Value (NPV) the Benefit-Cost ratio (B/C) the Pay Back period (PB) is presented the NPV at 4902971 baht B/C 3.72 and PB 2 year (with the Internal Rate of Return; IRR 49.7 percent).

The research on local wisdom in local Phetchaburi food of elderlies in Ban Huay Sai Nue to transfer and enhance learning capacity through online learning system is both quantitative and qualitative. It aims to collect local wisdom in local Phetchaburi food from both knowledge and direct experience of elderlies in Ban Huay Sai Nue Cha-am City Municipality Phetchaburi province in order to transfer the local wisdom to youths in Ban Huay Sai Nue and nearby areas as well as to develop local food recipe and procedure in both image and video formats through online learning system to enhance learning capacity of youths and other people. The target group was members of elderly group in Ban Huay Sai Nue which was divided into the major target the minor target and the recipents of technology transfer. Tools used in this reearch included a structured interview form and food recipe recording form. The research was divided into 4 main steps: selection of local wisdom collection of local wisdom transfer of local wisdom and distribution of local wisdom. Results of the research show that the target group selected 12 food recipes 8 dessert recipes and 2 drink recipes. The local wisdom was demonstrated by 9 members of elderly group in Ban Huay Sai Nue. The technology was tranferred to 40 students on Tessaban 6 School Ban Huay Sai Nue Cha-am City Municipality. Results of achievement test showed that trainees’ post-training knowledge was significantly diferent from pre-training knowledge at statistical level of 0.05 and satisfaction in the training process was highest in overall.

The research on the process of supply chain management standard goods distribution and marketing of the meat processing industry in Thailand to support the ASEAN Economic Community was aimed (1) the process of supply chain management standards goods distribution and marketing of the meat processing industry in Thailand to support the ASEAN Economic Community and (2) to determine the consistency of a causal model that influenced the process of supply chain management standards goods distribution and marketing of the meat processing industry in Thailand to support the ASEAN Economic Community with the empirical data. The variables used in this study were the independent variables including the availability and the readiness of the entrepreneurs. The mediator variables were the raw material transportation management and safety standard. The dependent variable was the supply chain management standard goods distribution and marketing of the meat processing industry in Thailand to support the ASEAN Economic Community. The researchers used a mixed method of qualitative and quantitative study. Questionnaires were used to collect empirical data from 350 entrepreneurs of the meat processing industry in Thailand. The statistical methods used to analyze data were the frequency percentage mean standard deviation and the analysis on the structural equation model and qualitative research methodology. The results revealed that the model was well consistent with the empirical data. The Chi – Square (2) value was 288.294 at the degrees of freedom (df) of 256 with the probability p-value equal to 0.081. The chi - square relative (2/df) was 1.127 with index of harmony (GFI) equal to 0.975 AGFI = 0.951 RMSEA = 0.017 The results showed that (1) the availability of resources had a positive influence on the transportation of raw materials (2) the availability of resources had a positive influence on safety standards (3) the entrepreneur readiness had a positive influence on the transportation of raw materials (4) the entrepreneur readiness had a positive influence on safety standards (5) the transportation of raw materials had a positive influence on safety standards (6) the transportation of raw materials had a positive influence on the supply chain management distribution and marketing and (7) safety standards had a positive influence on the supply chain management distribution and marketing of halal meat processing industry in Thailand to support the ASEAN Economic Community. The findings suggested that the meat processing industry should focus on the supply chain management distribution and marketing by promoting personnel deeper understanding to develop halal food. The government should also support the halal food industry as well

This paper presents an assessment of the quality of electricity transmission and distribution system to supply power to the industrial area. The objective is to analyze the power quality that customer in the industrial area need high level. By analyzing the power quality of Provincial Electricity Authority (PEA) in transmission system 115 kV distribution system 22 kV and 400/230 volt in Rojana industrial park from power quality meters. The study concluded that the phenomenon occurs continuously consist of RMS voltage power frequency voltage unbalance short term flicker long term flicker Harmonic meet the standards applied to all. The phenomenon occurs temporary consist of transient voltage dip voltage swell interruption in the conclusion the power quality problems caused by voltage dip most especially with loads which are sensitive to voltage. From the moment the measurement showed that the voltage dip on transmission system 115 kV maximum of 19 times. The voltage dip that occur including three voltage level of 30 times there are events that do not pass SEMI F47 standard 12 times or 40%.

A distributed generation is a small-scale Installed in the customer density sources. The benefits of distributed energy resources is one example. To improve the reliability of power distribution system for the better. The increased reliability of power distribution system that is connected to the source of power distribution efficiency depends on the size of the supply and installation of power distribution are considered appropriate. To Evaluation the reliability in distribution system with the main purpose is to the minimization for customer interruption cost. The technique employed to minimization problem for customer interruption cost in solved by the developed tabu search algorithm together with reliability worth analysis that provide an indirect measure for cost implication associated with power failure. The developed methodology is tested with a distribution system of Roy Billinton Test System (RBTS) bus 2. Numerical results from the tests demonstrate that distributed generation can be used to promote economy and reliability of the distribution systems.
