Complex of the project documentation on a feed circuit and sectionings of traction network for Moscow Metro

The Optima group takes part in project implementation of construction of new stations of the Sokolnichesky line of Moscow Metro. One of the tasks solved by the Optima Group is development of a full range of the project documentation on a feed circuit and sectionings of traction network of sections under construction. At the same time essential attention is paid to reliability of system operation of traction power supply, automation and scheduling of objects of Moscow Metro in different operating conditions. As the contractor of the project Optima Transport – structural division of the Optima Group which specializes in complete solutions in the transport and telecommunication industries acts. According to the agreement, Optima Transport will be engaged in development of the design estimates according to the section "Traction network 825" for construction of the facility: Sokolnichesky line of St. "Southwest" - the station "Rumyantsevo" - the station "Solntsevo" (Rodnikovaya St). Stage 3 "Section: the station "Troparevo" - the station "Rumyantsevo" - the station Salaryevo".

When developing special attention is paid to uninterrupted operation of system operation of traction power supply and traction network when providing a reliable current pick-off irrespective of the motion speed of trains, climatic and atmospheric conditions. Failure or failure of any element of a system can cause, at least, violation of the set train schedule that in the conditions of the megalopolis and constantly growing load of transport infrastructure of the capital can lead to essential discomfort of passengers. To avoid it, specialists of Optima Transport make repeated modeling of different options of system operation of traction power supply, provide control of all blueprint stages and apply control systems of work of traction power supply as uniform object, and is step-by-step. For this purpose specialists of the Optima Group and the staff of MIIT constantly improve the methods of calculations and model of elements of a system of traction power supply which are a part of the developed software package.

For a system design of traction power supply and a feed circuit and sectioning of traction network of sections of the Sokolnichesky line of Moscow Metro specialists of Optima Transport use unique methods of calculations which, in particular, allow to execute simulation modeling of a system of traction power supply and to control tension on the current collector of each electrorolling stock passing on section in any point of its movement and also to include and disconnect any elements of a power chain of traction power supply, imitating any forced operation modes. The software package capable to model system operation of traction power supply as a uniform object is the cornerstone of design methods.

Development of the project documentation is going to be completed at the end of April, 2013.

Let's note that the Optima Group – one of the few Russian system integrators having experience of implementation of difficult projects for the subways of Kazan, Omsk, Volgograd, Almaty, Nizhny Novgorod, St. Petersburg.

"To provide desirable regularity of the movement and reliability of work of the capital subway, it is necessary to apply modern technologies and the latest equipment, - the CEO of Optima Transport Garmazhanov Dmitry says. – Participating in the project on construction of new stations of the Moscow subway, we use not only own, but also international experience of the largest transport companies, continuously we improve existing solutions in cooperation with the lead industry scientific institutions. Our efforts are directed to providing the high level of service, comfort and safety of passengers".
