Poweline commununication for smart communities

Many communication devices are available in the Smart Community Lab, such as: PLC modems; PLC coupling system prototypes; GSM/GPRS modems; Automatic Meter Reading systems. Moreover, a reduced scale medium voltage power line is also available, which includes: MV cables; power transformers; capacitive dividers and power line communication (PLC) couplers of different size and manufacturers.
With the above mentioned devices and the instrumental equipment, measurement and performance tests can be implemented of different communication solutions for medium and low voltage distribution networks. Moreover, test campaign can be also performed on field, thanks to an agreement with the energy distributor system operator of the islands of Ustica and Favignana.
• Commercial and prototypal PLC coupling systems
• PLC coupling system interface prototype board (patent US08896393)
• Voltage detecting systems and MV cables

Anechoic Chamber – EMC facilities

In the Smart Community Lab two facilities are available to study the electromagnetic compatibility (EMC) of an equipment under test (EUT): a shielded electromagnetic semi-anechoic room and a GTEM 750 cell. The semi-anechoic room has dimensions of 9.4 x 6.4 x 5.55 m3. Emission and immunity radiated tests, compliant to the international standards, can be performed in the frequency range from 30 MHz to 18 GHz. The GTEM (Gigahertz Transverse Electromagnetic) 750 cell is a EMC test chamber used for radiated test in the frequency range from 0.01 MHz to 18 GHz.

• Semi-anechoic room door area of 2×3 m2.
• The distance between the EUT and the antenna is 3 m

Power electronic converter tested within a GTEM cell

Prototypes of power electronic converters for renewable generation, storage systems, vehicle applications are designed, built and tested in our laboratory. The power converters have the following features: high efficiency, high power density, high dynamic performance, low input/output harmonic distortion, high conversion gain. Suitable control laws are selected/developed and implemented by a  dSPACE® card  model DS1103 or Altera/Xilinx FPGA boards.

Test bench for assessment of EMI filters

It is composed of a PWM IGBT Voltage Source Inverter (VSI) that can supply three-phase induction motors up to 3 kW. The VSI is based on a STGIPS10K60A smart power module and on an Altera Cyclone III FPGA board, implementing the PWM modulator. The test bench can be used to verify the performance of passive and active EMI filters and to test Common Mode Active Compensators used for increasing the reliability of electrical drives.

Solar Simulator

The solar simulator is used for characterization of any type of PV cells and modules (e.g. crystalline silicon, amorphous silicon, polymeric, DSSC, etc.) up to 700 W/m2 solar irradiance level. The solar simulator is based on six metal-halide lamps. The illuminated PV panels can be connected to electrical loads directly or by electronic power converters to properly test the electrical interactions and to select/develop the most suitable control technique.

Different Intelligent Electronic Devices (IED) are available for measurement and control application in smart communities (smart cities and smart grids). SCADA software, distributed measurement systems and communication bridges are used to perform the remote management of the power flow in smart cities distribution networks. New prototypes of interface protection system (IPS) allow to remote control the distributed generators to vary its power production and power factor, for the stability of the medium and low voltage distribution network. Real tests can be performed in the two demonstrators of smart grid developed in cooperation with the energy distribution system operators of the island of Ustica and Favignana.

The RIM is mechanically coupled to a brushless IMPM machine drive, brand Control Technique ®, acting as active load, which can be operated either in torque control or in speed control mode. In motoring mode, the VSI is supplied by a 3-phase uncontrolled diode rectifier. In generating mode, the VSI is supplied by an additional VSI. In this case, the IMPM can be operated to emulate any prime mover (e.g. diesel engine, wind turbine, marine current turbine).
