POWER-SYSTEMS
We were born the power electronics and continuous innovation on products was our mission. Since the 80s, we focused on the switching technology and the modularity of the solutions. In the design of our systems we pay extreme care to the improvement of energy efficiency and reduction of emissions of harmonic disturbances in the network. Our energy stations with digital control guarantee the maximum compatibility with the power network without the use of harmonic filters and power factor correction. In the sector of traction power systems we offer the AC/DC conversion solutions for all transport systems according to international standards. We provide smart solutions for energy savings such as recovery energy inverters for regeneration of braking energy of trains or automatic braking systems with fixed resistors in substation. Powecon also produces a series of power equipment dedicated to the electrical traction of traction such as AC/DC rectifiers, multi frequency converters at 50Hz and 16,67Hz, static switch as overvoltage protection of the rail.
EPM
ENERGY STATION
Energy station to supply dc critical loads. The energy station are composed on AC/DC switching rectifiers to guarantee PF> 0,95 and efficiency > 0,9. Energy Station can be at single branch or at double branches. Redundancy in AC/DC rectifiers by paralleled hot swappable modules. Energy Stations are equipped with charger controller to takes care life cycle of the battery.
CHP1
CHOPPER CURRENT REGULATOR 250kW
DC current and voltage regulator to get a high precision in providing power. Complete system solution AC/DC with a polyphase controller to get a complete range of voltage regulation from 0 V up to ceiling voltage. The solution fit for industrial process where precision in delivery of power is mandatory. Powercon has a reference of a 300V/250 kW converter but other power ranges can be provided.
TRACTION – RDZ
AC/DC TRACTION DIODE RECTIFIER
Traction rectifier with silicon diode, natural air cooling, twelve or six pulse reaction. Voltage range from 750Vdc up to 3,6kVdc and several MW of power rating. Solution in IP00 or in metal enclosed IP3x enclosures. All the rectifiers are designed, manufactured and tested according with EN60146, EN50328 and EN50123.
TRACTION VCR
AC/DC TRACTION VOLTAGE CONTROLLED RECTIFIER
Traction rectifier to get voltage regulation of the DC output by means of controlled thyristors. The thyristors are clamped on double side aluminium heat sink connected by aluminium bus bar to get a Graetz bridge solution. The control of the rectifier is made by electronic card and digital regulation of the output voltage. Complete solution with rectifier transformer are available for metro line 750Vdc and 1.500Vdc or mainline 3,6kVdc.
RECON
REGENERATIVE ENERGY BRAKING SYSTEM
With RECON line, Powercon provides wide range of solution for regenerative braking system. DC/AC inverter connected to the grid as natural grid commutation or more sophisticated IGBT bridge with AFE controller in order to get PF close to 1 and low harmonic emission. These solutions can be suitable for existing substation or in new traction system.
ABR
WAYSIDE AUTOMATIC BRAKING RESISTOR SYSTEM
When the trains are braking the motors turn to be a generator and surplus of energy come to traction line and traction voltage arise over rated value. Thanks to its fast controller the Automatic Braking System switches on some large power resistors in parallel to traction line and keeps voltage at stable value. ABR is mandatory for test benches of trains and light rail systems.
ST_OVP
ACTIVE NEGATIVE OVERVOLTAGE PROTECTION
It is a real active overvoltage protection of the negative bus of the substation. This is a full digital version of standard OVP w/out any mechanical moving parts. The power electronic device switches negative bus to ground in few microseconds according with EN50122. The electronic device is able to re-open the connection even if some hundreds of amps are still flowing down earth. Rated current 35 kA x 250ms.
MULTI_V
STATIC VOLTAGE CONVERTER 50Hz and 16 2/3Hz
Static conversion group to provide energy to monophase loads at 50 Hz and/or 16 2/3 Hz. Clever solution for test benches or large train depot to supply different rails branches at different voltage level and different frequencies. High compatibility with upstream network no voltage unbalance and low harmonics emission.
