Mitsubishi Electric goes large with video wall in Belarus

The 11.2m wide by 3.5m high video wall was installed in the National Dispatching Centre of the Republican Unitary Enterprise ODU, the organisation that manages the national unified energy system of the Republic of Belarus. A total of 21 Mitsubishi Electric VS-80PE78UA 80" DLP cubes were used, in a 7 × 3 configuration, delivering a total resolution of 9800 × 3150 pixels.

At 80", each projector unit is considerably larger than the 70" or 72" displays more normally found in control rooms. The extra size is designed to improve operator visibility, while enabling exceptionally low running costs. Operating in Advanced Eco mode, each projector delivers a brightness of 860cd/m2, while still achieving a remarkably low power consumption of just 80W, making them currently the most energy-efficient on the market.

Moreover, in this mode the LED light source is rated for a minimum of 100,000 hours, or 11.3 years, of continuous operation. Mitsubishi's air-cooled projector technology requires no routine servicing, reducing maintenance costs to practically zero. Furthermore, the highly efficient projectors produce little heat, thereby reducing the load on the HVAC system. Rear access to the VS-80PE78UA cube means that the maintenance area behind the video wall can be maintained at a constant temperature of 18degC, while temperatures in the control room are at a more comfortable 22-24degC. Isolation from fan noise also improves operator comfort.

Thanks to the generous size of the video wall, the diagram of the entire power system and detailed information on its status is now clearly visible to the dispatchers. With all the essential data at their fingertips, the dispatchers are now able to monitor the network, adjust parameters and control power generation far more efficiently. In the event of an accident or malfunction, response times have been reduced and easier access to data ensures better decision making to recover network operability.
