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).

This thesis aims to study the optimization of the supply fuel system of pipeline by improving the pumps system from use pump size 1850 kW (2 pupms) and use only control valve. We design new system by use pump size 1850 kW (2 pumps) with variable speed motors (VSD). In this way we can control stability of opening and closing of the valve at 100% and use adjusting of the frequency of VSD as follow typing of fuel. To analysing of efficiency system we will use fuel 4 type that have different coefficient of density are JET A1 Disel B91 and B95. And then we compared the relationship between the quantity of each fuel per time and usage of power for the old system and new design that we found the new design as analyze the result and as follow the theory of Affinity Law have the value of efficacy more than. And it also can save energy cost to 52.13%

: This research focus (1) to design and development of packaging for processed products from Rice varieties Rice Berry (2) to promote and increase the value tour ecological economy (3) to test the satisfaction of consumers who have to the product packaging processing of Rice varieties Rice Berry the samples is the public to shop for health in the supermarket Golden place branch Rama 9 number of 334 people divided by the survey draft design is at a time 167 people and expert printing design packaging and materials 5 and tool operators research 1) questionnaire the first comment design draft for the samples to use as a guide to design body work package and assess the quality step work package design 2) questionnaire satisfaction survey for the samples with a draft of the packaging product 1] Rice Berry 2] candy Tootsie processing of Rice Federation of Rice Berry 3] Rice gluten-processing of Rice Federation of Rice Berry the data were analyzed using how to sum up operators with the lectures mean and standard deviation findings summarized as follows: (1) The attention to the materials used in the production of plastic packaging materials. Create a frame on one floor and a label to indicate the product description. Experts and samples Pay attention to the style and material of packaging SET A1 is plastic material selection 63 percent representing 37.70 (2) effect of assess the design of the package herbal Thailand overall found that the samples comments to form set a1 the evaluation of design in the high level with an average equal to 3.76 3.76 s.d. = 0.69) shaped as tree easy-to-use nature of close to weep and the site label use printing process 4-color design in accordance with the regulatory to produce a clear used patterns graphics media to “individual product type” logo of the product to reflect the English view the delicacy colors used as a couple color with color of the paper make sense naturally in the core of sustainable development research this can be adjusted in step process used nature of type 1 color to save the cost of production in the part of the structure. If there is eminent the bent to develop I-oriented wisdom to comply with the material in the local structure can be used as erosion siege basketwork that will help to create unique local with self-esteem.

In general the measured resistance with a digital multimeter. Users tend to be measured and then displayed on the screen to the user regardless of the value that is accurate or not. The value displayed on screen digital multimeter may be incorrect. As a result from wires access point measurement and other factor that affect to the value of measurement. Thus the study of factors that affect the measurement to get the accurate and more precise and also can be used in the operations. According to international standard quality system requirements for ISO are clearly on the meter or the measuring device must be calibrated and in the certificate specifies the gain calibration and the uncertainty of measurement. Therefore it is necessary to evaluate the uncertainty of measurement to comply with the standard splash. This thesis presents a study of the effect to the measurement resistance in 0.01 ohm to 100 mega-ohm by direct measurement for 2wire & 4wire Loading effect Using different kinds of conductors Thermal EMF and the stability of the resistor. Include the statistical analysis was used to estimate the uncertainty. From this study can be applied to measure the resistance in a variety of accurately and precisely.

Education and research is being Develop material that is mixed between rubber and rubber tree’s leaf for product designing. For product design This study is the use of a water timber with a rubber material. For use in product design Type of use and home decoration. In order to achieve the objectives of the research. The research was conducted by researchers at various stages. Data analysis and presentation. In the first part of the research questionnaire has been prepared for the development of product design. The study showed that the structure and the rubber leaves are fragile. It has adopted a water timber to merge. The experimental trial showed that the water timber formwork period is a major cause of water in the rubber sticking to the timber structure. When the latex has chemical and log Waldemar Carlo Night a period of use should not exceed three months at a water timber should be done with low viscosity. The color of the water timber must have a milky white. The collected data before designing it. The researcher has prepared all the tools of the 150 series found that most respondents as guest female age range 25-45 years as the rubber leaves of 94 percent 62.7 opine that the rubber leaves can be. made products of 5-10 species and the collection of data about materials latex with a rubber to make products from those carrying ask 150 people are of the opinion that it should make products partition 32.7 percent secondary. followed by the production of upholstered furniture 20.7 percent and 14.7 percent from the wallet to store data the researcher chose to put the material into a water timber with a rubber curtain room couch and wallet. When the prototype the researchers collected data on products made from latex and rubber leaves a series of 100 questionnaires showed that most of the respondents were female. Between the ages of 25-45 years the average undergraduate. There were government officers And have a monthly income of less than 5000 baht by the majority of respondents thought that. Rubber and rubber leaves the work piece is in good shape. Durable medium Can be used to make the products have 10-50 species with characteristics of both latex and rubber leaves. And all should be improved The research found that people are more interested in a piece of sheet material from a water timber with a timber. For product design Due to a combination of natural materials as a new material with a rubber-patterned rubber leaves a unique structure. It can also be improved by a more specific latex formulation. To be able to make the product even more.
