WEPPD040	Power Saving Schemes in the NSRRC	2600
	J.-C. Chang, Y.F. Chiu, Y.-C. Chung, Y.-C. Lin, C.Y. Liu, Z.-D. Tsai, T.-S. Ueng NSRRC, Hsinchu, Taiwan
	To cope with increasing power consumption and huge power bill of the Taiwan Photon Source (TPS) in the near future, we have been conducting several power saving schemes in the National Synchrotron Radiation Research Center (NSRRC) for years. This paper illustrates the power saving results and future schemes. The power saving schemes include optimization of chillers operation, power requirement control, air conditioning system improvement, application of heat pump, and the lighting system improvement.

WEPPD042	The Grounding System at TPS	2606
	T.-S. Ueng, J.-C. Chang, J.-R. Chen, Y.-C. Lin NSRRC, Hsinchu, Taiwan
	An elaborately designed grounding system has been installed under the TPS construction site. The ground grid was installed sector by sector to comply with the building construction schedule. The ground resistance measurement of each sector was carried out right after the grid installation. The final ground resistance measurement for the whole grounding system was performed also right after its completion. The measured ground resistances of each sector were used to estimate the final TPS ground resistance, and it was compared to the final TPS ground measurement result. Also, the analysis with computer software is used to justify it. The low impedance of TPS grounding system, < 0.15 ohm, is to insure the safety of TPS personnel and instrumentation, also, to reduce the noise of electronic devices.

WEPPD043	The Studies of Power System Harmonics at TLS	2609
	T.-S. Ueng, J.-C. Chang, Y.F. Chiu, K.C. Kuo, Y.-C. Lin NSRRC, Hsinchu, Taiwan
	The power system harmonic distortion in the utility system of NSRRC is investigated for improving the power system performance. The monitored power quality data at the point of common coupling is examined and compared with industrial standards. In addition, the harmonic characteristics of electric power for the accelerator magnets and adjustable speed drives which contribute the most harmonics are analyzed. Furthermore, the approach to mitigate the harmonic effects for improving the power quality is studied.

	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 will be completed in the end of 2011. The whole construction of the utility system is scheduled to be completed in the end of 2012. Total budget of this construction is about four million dollars. This utility system presented in this paper includes the electrical power, cooling water, air conditioning, compressed air and fire control systems.
