This paper shows the new technique of tracking Maximum Power Point (MPP) that is faster than P&O one. Furthermore, it can reduce the swing of MPP but P&O technique never deal with. This technique uses automatically selective technique between P&O and Lookup Table to reach MPP. At first, the controller selects P&O technique to track MPP and record the data on relationship between temperature and duty cycle into the Table. When the data in the Table are more enough and the recent temperature value is under defined condition, the controller will change P&O to Lookup Table technique automatically. However, the recorded data in the Table will be reset every day for tracking MPP accurately.

This paper discusses signal transmission in the grounding system. During online partial discharge (PD) measurement for the high voltage (HV) apparatus, various PD pulse currents recharge the dielectric of HV apparatus when a PD occurs. One of the noise typologies that affects PD patterns is called the cross-talk, that is, discharges that appear in the measured point due to coupling from another point. In order to study the cross-talk signal, the two PD measuring circuits which are circuit no.1 and circuit no.2, on the same grounding system in the HV laboratory were performed. The distance between two PD measuring circuits is about 20 meters. The artificial PD models were utilized to generate the PD signal injecting to the test circuit no.1, while the cross-talk signals were investigated in circuit no.2. The HFCT sensors were used to measure the PD signal in circuit 1 and the cross-talk signal in circuit 2. The measurement results found that the cross-talk signal transmission in grounding systems provides a bipolar PRPD pattern, and the pulse waveform shows an oscillation shape. Moreover, onsite PD measurements of the generator steam turbine were studied. It is noticeable that the knowledge about cross-talk phenomena in grounding systems can help the PD verification and location for online PD measurement.

This article presents a shadow oscillator with quadrature-phase outputs. The proposed circuit employs the voltage differential transconductance amplifier (VDTA) and two grounded passive elements. The frequency of the oscillation, as well as the condition of oscillation, are accomplished through the tunning of the gains of the external amplifiers. Therefore, frequency adjustability can be performed without the effect on the biquad cell which is the main feature of the shadow oscillators. The results from the PSpice simulations employing the CMOS circuit level are included to verify the proposed quadrature shadow oscillator configurations.

In the past, Coaxial cable was the signal cable used to transfer computer data. However, coaxial cables are now being modified for use in the high voltage coaxial cables to increase the security of power transmission in various areas. In addition to increased security, there is also an issue of stability maintenance and many perspectives as well. Because the cable that used to be utilized is still insulated. Therefore, Partial Discharge (PD) can still happen in the electrical system. This paper presents the PD propagation within the coaxial cable simulated via PSCAD/EMTDC program and carried out with RG-58 coaxial cable in a laboratory by testing the propagation of the PD pulse according to the conditions of different cable distances. From the experiment, the calculations will be reversed by considering on the differences of the time manner that PD pulse flows on the cable. The time reference point that the research studied has 2 points which are Peak to peak and Time of arrival(TOA). The comparison between simulation and experiment indicated the similar results with slight discrepancies caused by factors that can be accepted. TOA has smaller errors comparing with the peak to peak point showing that PD pulse flowing on the cable is attenuation and dispersion to the tailing wave part. That's the reason using Peak to Peak is a time reference point that has more errors. A thorough study of PD propagation is useful for in-depth analysis to locate the PD source accurately. As a result, the defect will be resolved on the spot.
在过去，同轴电缆是用来传输计算机数据的信号电缆。然而，同轴电缆现在正在被改造成高压同轴电缆，以增加各个领域电力传输的安全性。除了加强安全之外，还有一个维护稳定的问题，以及许多方面的问题。因为以前使用的电缆仍然是绝缘的。因此，局部放电(PD)仍可能在电力系统中发生。本文利用PSCAD/EMTDC程序模拟了PD脉冲在同轴电缆中的传播，并在实验室中用RG-58同轴电缆进行了实验，测试了不同电缆距离条件下PD脉冲的传播情况。从实验来看，考虑到PD脉冲在电缆上流动的时间方式的差异，计算将被逆转。本研究研究的时间参考点有两个点，分别是峰到峰和到达时间(TOA)。仿真结果与实验结果比较表明，仿真结果与实验结果基本一致，但存在可接受的因素导致的细微差异。与峰值点相比，TOA误差较小，说明PD脉冲在电缆上的流动是对尾波部分的衰减和色散。这就是为什么使用Peak to Peak是一个有更多误差的时间参考点。深入研究放电传播规律有助于深入分析和准确定位放电源。因此，缺陷将当场解决。

This paper presents a study of remote control (RC) quadcopter and RC fixed-wing radar cross section (RCS) estimation with L-Band primary surveillance radar (PSR), working at 1215–1350 MHz. Both RC were tested in an outdoor environment by using vector network analyzer which set up in monostatic radar type. The results illustrate a characteristic of RC quadcopter and RC fixed-wing with the channel impulse response in L-Band primary surveillance radar at each angle in term of the RCS estimation. The RCS value when using the PSR L-Band frequency range changed with the structure. Moreover, overall, the RC quadcopter and RC fixed-wing RCS values are approximately the same, possibly due to the fact that both of them are made of plastic.

Thailand 2015 Alternative Energy Development Plan declared that 1,280 MW of electricity, 1,283 ktoe equivalent of heat production, and 4,800 ton/day transport biofuel would be sourced from biogas by the year 2036. To understand the current situation, Thailand biogas production potential from Napier grass by region was investigated. Napier grass was assumed to be cultivated only on the unused land. Geographic information of land use and soil type was overlayed on the country map to identify suitable Napier grass cultivation areas. Annual accumulated precipitation of each province was also taken into account to calculate the Napier grass crop yield. The study shows that Napier grass could be cultivated in all parts of Thailand. At present the Napier grass crop yield and biogas production potentials are found to be 189,237,760 ton/year and 11,354 million m3/year, respectively.

Positioning uses radio waves such as AM, FM, telephone, and wireless signals. Which have been studied by many research for this thesis, consider finding positions using signals. The digital terrestrial television signal was used for positioning. The measurement model is designed with 121 positions covering an area of lO× 10 square meters by installing an antenna receiving height of 1 meter for reference height and 6 meters as specified by the NBTC. The distance from the transmit antenna to the receiving antenna is about 26 kilometers, using spectrum analyzers to measure and collect the results for analysis and compare the distance errors by using a fingerprinting technique and clean algorithm and a clean algorithm to get the most suitable signal. It can be seen that the distance error is reduced. So, it will be more accurate and the basis for future studies. Moreover, it can locate more accurately using digital terrestrial television signals, The DVB-T2 standard digital terrestrial television signal and fingerprinting technique, and the CLEAN algorithm.
