e-terragridcom TPI is an integrated teleprotection module for e-terragridcom T390 power line carrier

customers’ critical applications must have dependable access to electricity.

Reliable and independent communication between protection relays is paramount in ensuring security of service, protecting the power grid, and maintaining protection scheme operability.

The e-terragridcom TPI provides an integrated Teleprotection to Power line carrier, that remains a 100% Power Utility controlled communication network.

As an alternative to full digital communication solutions, Alstom Grid offers an innovative product for significant improvements in communication reliability in the electrical network.

With its dual path communication channels, the e-terragridcom TPI can deliver maximised performance according to customer requirements, drawing the benefits of an optical digital link in parallel with the Plc link.

Communication interface redundancy and connectivity

To improve security and reliability of Teleprotection commands, the e-terragridcom TPI offers the option of digital paths concurrently to Plc thus, improving the Probability of missing commands (Pmc) and Transfer Time (T0).

Furthermore, in response to key requests from customers, logical operations can now be applied to commands sent simultaneously on all available communication links.

At the reception side, an “oR” function can be applied on the commands received on a different path to trip the corresponding output The output is activated by the first received command from either link.

●● In terms of Pmc, reliability is improved by the fact that the 2 links operate in parallel

●● Transfer time (T0) is the best of the two links

Communication link options

The e-terragridcom TPI can be equipped with an optical SFP module for “inter or intrasubstation“ communications, allowing direct connection of the e-terragridcom TPIs or to a multiplexer compatible with Ieee c37.94 without converter or other intermediate equipment.

Also, e-terragridcom TPI connectivity can be expanded with the addition of electrical communication interfaces over V11/ X21, G703-1 64 Kbits/s and G703-6 2 mBits/s.

Modular architecture

The Plc T390 modular architecture can include up to two e-terragridcom TPI modules.

●● The 1U height e-terragridcom TPI module offers the largest number of inputs and outputs for an integrated Teleprotection.

●● each e-terragridcom TPI module is equipped with eight Inputs and 14 Heavy Duty outputs. They are freely programmable through the Human machine Interface (HmI) as main output, copy, or alarm. capacity to activate directly some circuit trip coils.

●● The e-terragridcom TPI module supports up to four commands in analogue mode, or six with priority scheme.

●● In digital mode, eight commands are supported, to cover more protection requirements, but which can also be applied to alarms and position information.

●● modular●● Integrated●● communication redundancy●● optimized bandwidth●● manageable

Teleprotection configuration and maintenance

The Teleprotection module is fully configurable through the graphical HmI of the Plc by the mean of an allocation matrix.

The HmI automatically recognises the e-terragridcom TPI module(s) and the Plc, which creates time and cost savings, since additional interfaces and specialised test and commissioning tools are unnecessary.

All facilities of the graphical HmI T1, such as remote configuration using the PLC’s IP address are available to the e-terragridcom TPI module. This includes compatibility with network management system compliant with SNmP protocol.

To cope with cyber security concerns, e-terragridcom T390 is the first PLC equipment to offer AeS encryption and this feature is also available with e-terragridcom TPI module to ensure secure information exchange between the HmI and the e-terragridcom T390.

Bandwidth optimisation

To benefit from the maximum ratio between transmission speed and bandwidth, the e-terragridcom TPI can transmit Teleprotection signals within the Plc digital communication stream. Since e-terragridcom TPI command signals cut the digital transmission a Fast Recovery Time algorithm allows resynchronisation of the Digital communication link after tripping commands that can be as low as 200ms.

The e-terragridcom TPI module can also work with analogue channels of 2; 2.5 or 4 kHz . Two possibilities are offered :

●● Dedicated band to Teleprotection command for best transfer time and security

●● ”Silent mode “ over the speech channel. At Idle state the teleprotection does not require any bandwidth. When a trip command is activated, only the channel dedicated to voice transmission can be cut depending on activation or non-activation of the boost facility

The e-terragridcom TPI architecture is already prepared for support of future hardware developments and, similarly, the firmware is “Ethernet-ready” (Teleprotection applications using IEC 61850). The firmware also incorporates future options to comply with a large range of customer constraints.
