There are two laboratories, the Energy & Machines Laboratory and Power Electronics & Drives Laboratory in this cluster.

Energy and Machines Laboratory (S2-B6C-04)
The Energy and Machines Laboratory is mainly for undergraduate teaching and research activities in areas related to energy technology and electrical machines. The facilities provided include ICAP/4 Windows Educational software, powerscope, LCR meters, gaussmeters and precision CTs. Synchronous machines, induction machines, dc machines and torque meters are also available for undergraduate teaching.


Power Electronics and Drives Laboratory (S2-B6C-06)
The Power Electronics and Drives Laboratory is well equipped for research activities in the Center for Smart Energy Systems (CSES). A comprehensive range of equipment suitable for measurement and analysis of fast switching high-voltage and high current waveforms is available. These include fibre optic voltage isolation systems, digital storage oscilloscopes, current probes and amplifiers, gaussmeter, impedance analyser and powerscopes. High voltage and high current dc power supplies, both unregulated and fully regulated, are available for investigation of power device characteristics, converter topologies and drive control techniques. A number of DSP and microcontroller development platforms are also used for research projects involving advanced digital control of induction motors, switched reluctance motors and brushless dc drives. The laboratory also has well-utilised computing resources supporting specialised software packages such as Maxwell 2D finite element analysis software for design of new motor structures, and power electronic circuit simulation software, such as Simplorer and PSpice for Windows. In addition, the laboratory has an arbitrary waveform generator, a 3.5-kW high-frequency amplifier, a thermal imaging system and several high performance dynamometers. The laboratory's other acquisitions include power device characterization systems, network/impedance analysers and time-stepping finite element simulators.

Laboratory Executives in Cluster 1.2

In Cluster 1.2, there are three laboratories, the Electric Power Research Laboratory (EPR), the Power System Laboratory (PS) and the System Protection Laboratory (SP). EPR is used mainly to support research activities in power system simulations, while the PS and SP house mainly undergraduate teaching facilities and are used to conduct research in low voltage distribution systems, protection, equipment condition monitoring and power quality studies.

Electric Power Research Laboratory (S2-B5C-02)
The laboratory is focused on power system operation and control, AI, real time knowledge-based bulk power system restoration, web-based applications, deregulated power market, robust non-linear controller design, power system reliability assessment, stability enhancement, DC/DC converter design and FACTS applications. To support these activities, the laboratory is equipped with two SunSparc 5, 50 personal computers, Sun Enterprise 4000, microcomputers, a 500-MHz digital oscilloscope, a digital transient recorder (32 analog and 32 digital inputs), a linear XY stage system, a DC-brushless server motor system and a real-time digital simulator (RTDS). Software packages available in the laboratory include RTDS simulation software, PSCAD, EMTDC, COMREL and STAREL.

Laboratory for Clean Energy Research (LaCER) (S2-B7C-05)
This laboratory focuses its teaching and research activities in the areas of planning, analysis, computer control and operation of distribution and low-voltage systems. Clean and renewable distributed generation systems, power quality analysis and improvement are also investigated in this laboratory. The laboratory is equipped with many personal computers, a 2-GHz digital oscilloscope, a network/impedance analyser, a LV electrical distribution training simulator with SCADA functions, a medium-voltage 22 kV feeder panel and a web-based power quality monitoring system. The LV simulator is particularly useful for distributed generation investigation. Power system analysis software packages include State Estimator, Security Analysis, Optimal Power Flow, Unit Commitment and a PSIM simulation package. Power quality improvement devices such as Dynamic Voltage Restorer (DVR) and harmonic active filter are incorporated into the simulator. The simulator, which represents a typical electrical wiring system in a modern building, also serves as a test bed for high-speed power line communication research.

System Protection Laboratory (S2-B7C-01)
The laboratory provides facilities for the teaching and research work in the areas of power system protection and on- and off-line condition monitoring of power apparatus. It is equipped with many modern measuring and testing instruments. These include a dc dielectric test set, a Schering bridge, a transformer ratio tester, a low resistance (milli-ohm range) measuring set, a stereo microscope with image capturing system, an insulation oil set up to 60 kV, a 100-kV ac/dc high voltage test system with HV divider, a temperature and humidity chamber, a dissolved gas extraction system using vacuum techniques, a gas chamber, an insulation diagnostic system-dielectrometry up to 0.001 Hz @ 200 V, a 100-pF, 100-kV capacitor, a partial discharge measuring system with developed calibrator, a 3-GHz bandwidth spectrum analyser and a 1-GHz bandwidth 4-channel digital oscilloscope with 1.5 GHz bandwidth probes, two three-phase clean sinusoidal sources, several microprocessor-based primary and secondary current injection test stations, and an assortment of protective relays. A S$70,000 PC-based package “Electromagnetic Simulator System” has been installed for the teaching of a final year design module.
Transformer gas-in-oil analysis, DGA, polarisation, depolarisation, harmonic currents, recovery voltage measurements, dielectrometry and partial discharge measurements, and frequency response analysis are some of the research activities initiated in the laboratory. The laboratory has been retrofitted for 100 kV high voltage testing in 2002. Field studies at Power Seraya, Power Senoko and Port of Singapore Authority are being done to evaluate the above-mentioned condition monitoring techniques.
