Regenerators series I-PTE

Product catalog summary

Introduction
The document discusses the Series I-PTE regenerators produced by PLUTON, used in metro traction substations. These regenerators, combined with dry-type transformers manufactured using RESIBLOC® technology, are designed to improve energy efficiency in metro systems.

Advantages of Regeneration
Regenerators help improve metro energy indicators by recovering energy during train braking, reducing overvoltage levels, facilitating ventilation modes, and saving up to 30% of electricity consumption. They allow energy to be fed back into the network, reducing overall power consumption.

Technical Specifications and Configurations
The regenerators can be connected to existing traction substations using a grid-controlled inverter and converter transformer. The document outlines two main configurations: a standard connection with a smoothing reactor and an autotransformer circuit. Each configuration has its own advantages and limitations, such as cost savings and capacity constraints.

Converter Section
The converter section is a thyristor six-valve bridge with a 12-pulse inversion circuit, offering advantages in harmonic composition over traditional 6-pulse circuits. The system is designed to meet international harmonic limits, eliminating the need for additional filtering devices.

Control System
The control system is based on the MC-40 microprocessor module, providing control, diagnostics, and protection functions. It includes various protections against short circuits, overheating, and voltage issues.

RESIBLOC® Transformer
RESIBLOC® transformers are used as converter transformers, capable of withstanding extreme temperature fluctuations and operating in high humidity and chemically polluted environments. They are recommended for new substation constructions to save costs and reduce payback periods.

Main Technical Parameters
The document provides detailed technical parameters for different regenerator models, including rated output voltage, frequency, cooling methods, and efficiency coefficients.

Overall Dimensions
Dimensions for various models of the converter sections are provided, detailing the layout and components such as earthing busbars and control circuit terminal blocks.

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 in...

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 voltage...

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 maintenance...
