This is an extension of the original FUEL SAVE system from 2015. Both FUEL SAVE systems (containers) are interconnected to the main circuit breaker to connect the PV input in the substation. The communication is done by the communication link between control cabinets (DT1, DT2) in both containers. COMAP InteliGen NT control systems for the control of diesel generators in the substation are interco…

Comprehensive solution for the mining traction locomotive electronics. For the main drives, the SEMIKRON SEMiX equipped inverters are based on the proven UNIFREM platform. For each locomotive drive, unique torque-speed vector control is used – the joystick on the control panel in the locomotive cabin is not only the speed reference, but also the torque reference. The torque between the individual…

In the rainwater pumping station are installed two independent screw pumps for drainage of rainwater. First softstarter SINAM 400/191 starts the pump motor #1. Second SINAM 400/191 starts the #2 pump motor. The control system for the rainwater pumping station automation includes controls for automatic control of pump switching, manual mode or manual mode to the level. The rainwater height is sense…

The compressor manufacturer in the Slovak Republic has had to solve the problem of testing its products for markets with 60Hz frequency. Based on its requirements, a special aingle-phase artificial AC mains was designed and manufactured to test hermetic compressors and condensing units. Output alternating single-phase voltage is measured by a special measuring circuit which is connected as a feedb…

This is a project made upon a special request from the customer. It involves two kinds of inverter – PV panel fed for on-grid operation and 48V battery fed for hybrid operation. The hybrid inverter serves mostly for self-consumption covering late in the evening and during the night. On-grid inverter is user for self-consumption cover during the day. The surplus energy is used for battery charging.

Custom designed laboratory for East Slovakian distribution company and Technical university of Kosice.

DC power supply for feeding the trollery wire for TLP class locomotives. One of several output voltages can be user: (UOUT1=1x325VDC, UOUT2=1x275VDC, UOUT3=1x225VDC). This rectifier is equipped with the line monitoring relay, so in case of grid failure the DC supply is turned on to increase safety. #NOFRONTPAGE#

GSE CONTROL je určený pre minimalizáciu odoberaného výkonu zo siete v objektoch, ktoré majú vlastný zdroj energie (fotovoltické alebo iné elektrárne) a majú aj vlastnú spotrebu. Menič vyhodnocuje impulzné S0 výstupy z elektromera pripojeného v bode pripojenia celého objektu do distribučnej siete, ktoré signalizujú zvlášť okamžitú výrobu a okamžitú spotrebu v objekte. Menič automaticky riadi tok en…

GSE CONTROL is made for minimization of grid power flow for the objects equipped with own energy source (PV or other power plant) and having a significant own consumption. The GSE CONTROL evaluates S0 outputs from the energy meter connected to the point of common coupling. GSE CONTROL automatically controls the energy flow between the battery and the three phase AC grid. There are several basic mo…

Fuel save system is installed in autonomous grid systems in remote area. Main source of energy are diesel gensets. To reduce the high fuel costs, a PV power plant has been built. PV power plant is very suitable and economically viable, because it is a very sunny region. To enable safe and reliable operation with the gensets, a special inverter software and control system have been designed.
