	There are more and more non-linear electronic equipments such as inverters using in facility nowadays. These non-linear electronic equipments let us achieve energy saving, but induce other electrical pollution to the whole power grid in contrast. Among these electrical pollutions, electric harmonic is the most common and harmful to power facility. Therefore, how to monitor the electrical noises from these non-linear equipments becomes an important issue. In this article, a set of power quality monitoring system based on FPGA (Field-Programmable Gate Arrays) modules and PAC (Programmable Automatic Controller) has been built because of their programmability and fast processing speed. By using this monitoring system, any abnormality in power system and its spectrum will be recorded thoroughly. On the other hand, the maintainer could follow the trace of noise and then propose a suitable solution to eliminate the electrical interference too.

	In order to maintain and operate a synchrotron radiation light source well requires quite a few efforts. All parts of the big machine, including vacuum system, all kinds of magnets, RF facility, cryogenic equipments, radiation security, optic devices and utility equipment must cooperate in harmony to provide high quality light. Any one of the above system contains lots of analog or digital signal transmission, not to mention the vast range of utility. Numbers of programmable automation controllers (PACs) are applied in utility system in TPS to ensure the utility operates normally. In addition to the high reliability and distribution, the flexible programmability of PAC is the most critical feature in this project. A well-designed program, Archive Viewer, provides a platform for showing these big data from all distributed systems. The architecture of the server system for utility is described in this paper as well.

	The construction of the utility system for the 3.0 GeV Taiwan Photon Source (TPS) was started in the end of 2009. The utility building for the TPS ring had been completed in the end of 2014. The final test and improvement had been completed in the end of 2014. The TPS is in commission and TLS is still in operation. Within limited manpower and budget, it is challenge to operate both utility systems stable and reliable. We provide good quality of electrical power, cooling water and precision air temperature. Power saving is also an important issue. The utility system presented in this paper includes the electrical power, cooling water, air conditioning, compressed air, and fire control systems.

WEPHA030	EMI Measurement for TPS Booster Kicker and Septum Systems	3179
	Y.-H. Liu, W.S. Chan, C.S. Chen, J.-R. Chen NSRRC, Hsinchu, Taiwan
	The purpose of this paper is to estimate the conducted and radiated Electromagnetic Interference (EMI) for subsystems in the TPS booster ring. A LISN (Line Impedance Stabilizing Network) system with a wide frequency range was conducted to measure the EMI spectrum of pulsed magnet system. The radiated EMI was tested by magnetic field probe, which the measurement frequency range is 100 kHz ~ 3 GHz. A stray current was tested by wide frequency current transformer in order to measure the conducted current for kicker and septum systems. According to the experiment results, the stray current could flow through the other subsystems or booster chamber, and it might be affected the stability of booster operation. Therefore reducing and eliminating the interference of EM waves will be a very important issue. The EMI prevention scheme will be continued.

WEPHA034	Commissioning of the De-ionized Water System for Taiwan Photon Source	3188

	The de-ionized water (DIW) system plays a critical role in removing waste heat from an accelerator machine. Through years of design and constructs, the DIW system for Taiwan Photon Source (TPS) was complete at the end of 2013, but it is important to confirm that the quantity and quality of DIW comply with the requirements of the accelerator machine. Testing, adjustment and balancing methods have been applied to verify that the DIW system for TPS can provide flow rates greater than 1659, 380, 1284 and 1238 GPM in the individual Cu, Al, RF and booster subsystems. The proposed system can supply DIW of quality such that the resistivity is greater than 10 MΩ-cm at 25±0.1 oC; the concentration of dissolved oxygen (DO) is less than 10 ppb.

WEPHA042	Commissioning of the TPS Cooling System: Testing, Adjusting, Balancing and Numerical Simulation	3209
	Z.-D. Tsai, W.S. Chan, Y.C. Chang, C.S. Chen, Y.-C. Chung, C.W. Hsu, C.Y. Liu NSRRC, Hsinchu, Taiwan
	The civil construction and utility systems of the 3-GeV Taiwan Photon Source (TPS) at NSRRC are ready for machine commissioning in 2014. To achieve a highly precise control of temperature, the thermal load must be carefully controlled and balanced. On analysis of the characteristics between the water pipes and the balance valves, a specified control philosophy can effectively adjust the pressure load on the branch pipes to balance the water flow. With regard to the air flow, we use a damper, baffle plant or variable air-volume (VAV) box to balance the air flow of each diffuser. Here we discuss the mechanism through a numerical simulation of the hydrodynamics and verify the practical influences of the testing, adjusting and balancing (TAB) for de-ionized water and the heating, ventilation and air-conditioning (HVAC) system.
