SynchroGuard's Protocol Buffer Messages

In SynchroGuard, real-time data exchange relies on protocol buffer messages exchanged over RabbitMQ. Thus, consuming and/or publishing protocol buffer messages on RabbitMQ is the preferred way to integrate third parties with SynchroGuard for real-time data exchange.

This repository includes the Protocol Buffer used in Zaphiro's platform and the generated code for GO and Python.

Available Protocol Buffer Messages

At the time being this repository includes the following Protocol Buffer packages:

• Grid package collects grid related messages, defined in zaphiro/grid/v1, which currently include:
  • Data protocol buffer package, that includes the following messages
    • Data: a single measurement data
    • DataSet: a collection of measurement data.
  • Fault protocol buffer package, that includes the following messages:
    • Fault: an abnormal condition causing current flow through conducting equipment, such as caused by equipment failure or short circuits from objects not typically modelled.
    • Line Fault: a fault that occurs on an AC line segment at some point along the length.
    • Equipment Fault: a fault applied at the terminal, external to the equipment. This class is not used to specify faults internal to the equipment.
  • Topology protocol buffer package, that includes the following messages:
    • Topology: an message represented an topology computed by the system.
  • Event protocol buffer package that define general event messages, inherited by:
    • GridEvent: a message that represent grid events.
• Platform package collects platform related messages, defined in zaphiro/platform/v1, which currently include:
  • Task: a task to be performed by an service in the platform.
  • Notification: a notification produced by a service in the platform.
• C37118 package collects messages related to the IEEE c37.118 standard, defined in zaphiro/c37118/v1, which currently include:
  • Conf2Frame: a Protocol Buffer used to store PMU configuration frames.
  • Stat: a Protocol Buffer used to store PMU measurement Stat.

All protocol buffers are documented in docs.

Examples

For your convenience, in the examples folder we provide Go code to:

• Produce and consume measurements (uses RabbitMQ streams).
• Produce and consume faults (uses RabbitMQ exchanges).

Requirements

• Golang 1.21
• Docker

Produce and consume measurements

Go

1. Set-up the infrastructure using make docker-start.
2. Launch the example make example-measurements-go
3. Press any key to stop.

Contributing to Protocol Buffers

Should you need to modify the protocol buffer message or add new ones, you will need to set-up the dependencies listed in Requirements.

Protocol buffers are versioned (current version is v1), and should be developed following best practices, as implemented by Buf and defined in Protobuf programming guides. In particular, it is important - even more within the same version - to preserve compatibility, to avoid services breaking up.

You find contributing guidelines here.

Requirements

1. Golang
2. Protocol Buffer Compiler
3. Go plugins for the protocol compiler
4. Buf
5. proto-gen-md-diagrams
