SFC for railway traction power supply in Moreton Bay

Body

In 2016, GE Vernova’s Power Conversion & Storage business delivered and commissioned the SFC systems for the Moreton Bay Rail link project in Australia. This was the first implementation of SFC technology in an Australian metropolitan rail network.

System overview

The project encompassed two independent feeder stations, each featuring a 15 MVA converter system based on Power Conversion & Storage’s proven MV7000 converter technology.
These converters are housed within a transportable substation building, which includes a control room, while additional supporting equipment is located externally.
A single converter block comprises the following main components:

Input 3-phase 4QS sub-inverter with three single-phase modules
DC link with an extensive capacitance
Output 1-phase 4QS sub-inverter with two phase modules

The core components of each sub-inverter are the press-pack IGBT modules, arranged in two phase segments and equipped with a patented pull-out mechanism, including the IGBT control amplifiers.

SFC system details

Transformer

The converter system design necessitates the installation of two transformers for each converter block. Both transformers are intended for outdoor installation and are equipped with an ONAN cooling system tailored for the hot weather conditions in Brisbane, Australia. The input transformer, rated at 33 kV and 50 Hz, features three output windings that directly supply the three inverter units. The output transformer increases the converter’s single-phase 14.7 kV output voltage to supply the railway with 25 kV at 50 Hz. A railway filter is connected to both the output of the railway transformer and its auxiliary winding

Cooling system

Each converter block is equipped with its own dedicated cooling system, which uses a glycol-water mixture to directly cool the power electronics. The cooling system is designed to operate in temperatures up to 45 degrees Celsius and features an enhanced water-air heat exchanger to manage the minimal temperature difference between the ambient air and the required inlet fluid temperature. Two water pumps are installed, offering 100% redundancy to ensure continuous circulation. These systems are monitored continuously, and the pumps are alternated every 24 hours.

Additional air conditioning is provided for the station premises

Control system

The internal converter control system enables the following operation modes:

Standard control in all four quadrants,
Phase shift operation, providing reactive power exclusively to the railway grid,
Parallel operation with the existing standard 50 Hz railway feeding system,
Isolated mode, where the system operates its own railway grid.

The control system supports both local and remote operation through a user-friendly HDM interface.

Advanced Motor Health Report

The Multilin Agile health report provides a quick snapshot of the motor operating and diagnostic information in an easy way to allow users to make decisions about health of the motor. Based on the graphical representation and trend values of the motor historical data gathered by the Multilin Agile, users can quickly identify process issues and maintenance requirements before damage occurs and costly repairs are required.

The motor health report quickly provides a motor operation summary with detailed information in seven categories.

Advanced Communications

Three communication ports are standard: a rear serial port providing remote communications, a front USB port and rear Ethernet for device configuration and management.

Two additional Ethernet ports can be ordered to achieve Ethernet communication redundancy.

Supported Communication Protocols Include:

Modbus (RS485 serial or Ethernet)
IEC 60870-5-103
DNP 3.0 (RS485 serial or Ethernet)
IEC 61850 Ed. 2 with concurrent serial connection
Redundant Ethernet protocols PRP, HSR, and failover also available with dual RJ45 or dual fiber media

Flexible Hardware

Space-saving 4U height with 4” (20TE) and 6“ (30TE) case size options
Wide choice of opto-isolated binary inputs and output relays
Binary inputs ESI 48-4 EB2 compliant – avoids spurious pickup from induction on field wiring
High density I/Os in various combinations depending on case size option
Ungrouped binary inputs for trip circuit supervision
Field upgradeable, avoiding costly hardware change
6” (30TE) models can accommodate:
- 1 x RS485/IRIG-B interface
- Up to 3 x RJ45/fiber optic ports for single and redundant Ethernet plus additional engineering access
- From 11 to 30 binary inputs, and 9 to 25 relay outputs, depending on the order code
4” (20TE) models can accommodate:
- 1 x RS485/IRIG-B interface
- 1 x RS485 additional interface
- Up to 3 x RJ45/fiber optic ports for single and redundant Ethernet plus additional engineering access

Simulation & Testing

To aid commissioning, a simulation feature is provided to test the relay’s functionality and response to programmed conditions, without the need for external AC voltage and current inputs. When placed in simulation mode, the relay suspends reading actual AC inputs, generates samples to represent the programmed phasors, and loads these samples into the memory to be processed by the relay. Normal (pre-fault), fault, and post-fault conditions can be simulated to exercise a variety of relay features. Other test operations - such as an LED lamp test for each color, contact input states, and testing of output relays - are also possible.

Application Model Selection

Model	Hardware Base	Intended Application	Case Size
P24NB	P24N	Motor Protection (current elements only)	20TE/30TE
P24DB	P24D	Motor Protection (current voltage & power elements)	20TE/30TE
