Energy and generation

Guaranteed power supply systems at power generation sites in Russia have a number of specific features due to the critical importance of ensuring the reliability and safety of both main and auxiliary equipment. These features are defined by regulatory documents such as PUE (Electrical Installation Code), GOST standards, and orders of the Ministry of Energy of the Russian Federation.

At energy and generation facilities, the key task of guaranteed power supply systems is to maintain control over power units and substations during any external grid failures. For essential circuits — auxiliary needs, relay protection, automation, operating current, and backup lighting — even brief interruptions are unacceptable. They may lead to equipment damage, line trips, and cascading failures. The challenge is further complicated by traditional DC busbar schemes, the combination of old and new systems, strict industry regulations, and demanding safety requirements, especially at sites with a high level of responsibility.

Voltag’s solutions for power and generation are designed around these challenges. Industrial UPSs, battery chargers-rectifiers, voltage stabilizers, and inverters are engineered to work in the existing architecture of power plants and substations, support joint operation with station batteries, withstand emergency modes and disturbances, and provide convenient monitoring and diagnostics. As a result, critically important control and protection circuits remain operational even in severe emergency scenarios, while operation and modernization of equipment throughout the entire lifecycle of the facility becomes more predictable and manageable.
