The technical solution of the project is to create a comprehensive autonomous energy module based on a mobile two-transformer complete substation (MKTP) with a voltage of 10/0.4 kV. This solution is designed for operational capacity backup and quick connection to existing city networks in emergency situations. Structurally and functionally, the solution is divided into several key technological blocks that ensure its reliability, mobility and high efficiency.
The basis of the complex is a block-modular metal structure (substation shell of the KTPMM type), divided into specialized compartments. It contains high (RU-10 kV) and low (RU-0.4 kV) voltage switchgear, modern switching devices, commercial electricity metering units (meters) and microprocessor relay protection and automation systems (RZA). The use of modern microprocessor protection and telemetry allows you to safely manage the load, monitor network parameters and quickly localize emergency areas.
The main working element of the substation, which provides voltage reduction to the consumer level (380/220V), are two power oil transformers, which are mounted in the corresponding transformer compartments of the module. The two-transformer configuration was chosen purposefully: it not only provides the necessary total throughput capacity to power critical facilities (such as pumping stations or boiler rooms), but also creates internal redundancy. In the event of overload or preventive maintenance of one of the transformers, the other is able to support powering the most priority lines.
To ensure the key requirement of the project — mobility — The entire complex is mounted on a single transport platform (or reinforced sled frame), which allows it to be quickly moved using a truck tractor or special equipment. The substation is equipped with unified nodes for quick connection of input and output cable or overhead lines. Such an engineering solution turns a classic stationary facility into a maneuvering crisis response tool capable of restoring power to an entire neighborhood or utility company in less than 24 hours.
