REGENERATORS, SERIES I-PTE

Converter sections, series I-PTE, produced by PLUTON together with dry-type transformers, manufactured by RESIBLOC® technology are applied as regenerators for metro traction substations. Advantages of regeneration Application of regenerators allows to: • improve metro energy indicators by regeneration of energy released during train braking (having regenerative braking mode in electric rolling stock); • reduce overvoltage level occurring during regenerative braking; • facilitate metro ventilation modes (studies show that application of dynamic braking dissipating the braking energy as heat...

Autotransformer circuit can be applied as another version of additional converter switching on. In this case, inverter is connected to the actual traction transformer via AT autotransformer. Disconnector (Q) allows taking regenerator out of operation without rectifier tripping if required. Number of disconnectors and autotransformers should be doubled for the 12-pulse version. This version can be recommended upon modification of actual substation under limited space conditions. Network 10 kV Traction substation Autotransformer Autotransformer Benefits of this version: • no separate medium...

Figure on the left shows switching and the ways of energy regeneration. Any time braking energy can be given via regenerator to medium voltage network, transferred over long distances and used by different consumers both auxiliaries (escalators, lighting, ventilation) and others. The latest developments in converter technology were used in design and manufacturing of regenerators, series I-PTE. This applies to the design of cabinet, converter power part, electrical installation, regenerator protection systems, diagnostics and control circuit design and technological solutions, as well as...

CONTROL SYSTEM Control system is based on MC-40 microprocessor module developed by PLUTON. This module fulfills control, diagnostic and protection functions of regenerator. A1 - Switchgear RU-10 kV Т1 - Converter transformer A2 - Invertor section 1 A3 - Invertor section 2 А4, А5 - Cabinet with reactors А6, А7 - HSCB cabinet Each CS has the following protections: • against internal short circuits; • against external short circuits; • input current limit by discrete-configurable setting; • time-current protection; • against invertor triggering; • against network voltage slump; • against power...

MAIN TECHNICAL PARAMETERS OF REGENERATORS * - cooling method, which uses natural air cooling of thyristors, and the installed in sections fans switch on automatically for a short time, when temperature rises to the set level, and switch off when the temperature decreases.
