Control rooms of the district power plants of JSC UEC located in all administrative districts of Moscow are designed to collect and process information on the condition of the substations and local cable networks, emergency notification for rapid troubleshooting, control of electricity supply to consumers, and are one of the most important means of ensuring the safety and uninterrupted supply of electricity.
Substation monitoring and control system of the dispatcher station registers deviation of monitored parameters from permissible values and, if necessary, issues an alarm message, based on which the dispatcher decides on prompt actions to eliminate the problem. At that, the more monitoring and control facilities the employees have, the more effective the measures taken. Continuous operation mode, large volumes of heterogeneous information, the need for comfortable working conditions - all this leads to special requirements for the equipment of dispatch centers.
Depending on the amount of information which must be shown on the video wall, two DEPO Videocube solutions were configured for control rooms: for installing video walls of 12 or 15 LCD panels.
The data coming from the substations are processed by a fault-tolerant cluster of two servers with data storage and a KVM console for their maintenance. After processing the information, the DEPO ReVision video controller outputs the data to the video wall.
Each controller has 12 or 15 video outputs (according to the number of connected LCD panels) and allows you to easily control the image output to the video wall. The controller is designed for continuous operation and has a dual redundant power supply with hot-swappable modules.
Video wall consists of 46-inch seamless LCD panels (size of one panel 1.0 × 0.6 m) mounted on special stands to ensure stability and provide ease of maintenance. Especially for this project, the standard mounting kit was modified in the DEPO Computers manufacturing facility, making it possible to attach video walls to the ceiling for greater reliability.
The dispatchers' workplaces monitor critical parameters of the substations and are equipped with computers with two 30-inch displays, which, like a video wall, display operational information about the subsystems monitored by the employee in question. Data exchange between the district control rooms and the Grid Technological Control Center is carried out via a secure wireless Internet connection.
All substation control system equipment has been connected to uninterruptible power supplies with a network control function to ensure operability in the event of a power failure.
