In 2018 PLUTON successfully implemented works on the project "Development of Dushanbe public transport".
Within the framework of the project PLUTON experts carried out retrofit of 3 trolleybus traction substations (TS-2, TS-4, TS-6), as well as equipment supply, including SCADA remote control system, for 6 traction substations (TS-3, TS-5, TS-7 — TS-10) of the State Communal Unitary Enterprise "Trolleybus".
The project was implemented with the support of the European Bank for Reconstruction and Development (EBRD).
The project was implemented under the conditions of operating power supply facilities without interruption of Dushanbe trolleybuses operation, and included the following types of works:
- development of detailed design;
- supply of required equipment and materials;
- carrying out dismantling and assembling works, commissioning;
- tests, trial run and startup of traction substations TS-2 (6 kV), TS-4 (10 kV), TS-6 (10 kV); tests, trial run and startup of new equipment at TS-3, TS-5, TS‑7 – TS-10;
- installation of telecontrol system at substations;
- development of Remote control center with installation of industrial SCADA-system;
- training of Customer's technical staff on operation and maintenance of new equipment.
Equipping of traction substations with modern telecontrol systems and deployment of SCADA-system allowed significantly improving prompt response level, it has become possible to continuously monitor power system key indicators state, as well as to remotely control electrical network circuit in normal, emergency and post-emergency modes. Besides, high-speed operation, control safety and reliability indicators were improved, high failure safety of the system and redundancy of critical components was provided, s well as maintenance costs were significantly reduced. This also significantly reduced response time on emergency situations in city electric transport power supply, as well as optimized the number of maintenance staff.
PLUTON traction substations equipment, including protection and control system, as well as auxiliaries equipment, meets international and European norms and standards.
