  National Synchrotron Radiation Research Center (NSRRC), Taiwan currently operates two synchrotrons, the Taiwan Light Source (TLS) and Taiwan Photon Source (TPS). The former one has been operated for more than 22 years, while the latter is in commissioning phase. We target of the beam current on 500 mA. Thus, the power consumption increases higher than ever. Currently, the contract power capacities of the TLS and TPS with the Taiwan Power Company (TPC) are 5.5MW and 7.5MW, respectively. The ultimate power consumption of the TPS is estimated about 12.5MW. To cope with increasing power requirement, we have conducting several power saving schemes for years. This paper presents our latest power schemes, which include installation of power saving fan for the cooling tower, adjustment of supply air temperature according to the atmosphere enthalpy, replacement of old air conditioning unit (AHU), power consumption control by the operation of chillers, and power factor improvement.

  For monitoring effectively the real time status of NSRRC's electric power system, an electric power quality monitoring system has been set up to measure the power quality of high voltage feeders, which includes the voltage/current phase, the variation of frequency, voltage sags and swells. The measured result will be analyzed and used to further improve the performance of power system. Furthermore, a partial discharge monitoring system was also installed to monitor the phenomena of electric discharges. Using the ultra high frequency discharge sensor, the magnitude and the pulse-per-second of discharge are measured and analysed. It allows the electrical engineers to diagnose the degradation of insulation of the electric equipment beforehand to reduce the power failure.
