and deployment security

Extensive predefined tests to ensure the quickest possible deployment

Context and Challenges

An important mining company needed to expand its electrical system, which included a main substation and a cogeneration plant. It was necessary that the pre-existing equipment, which had different technologies and protocols, communicated with the new equipment incorporated to the system. A standardized operating interface needed to be developed to allow fluid operation of the entire system. To do this, the following challenges had to be overcome:

  1. Integrate equipment that converged on different protocols: IEC 61850, DNP3, Modbus TCP and Modbus RTU
  2. Meeting deadlines, which were reduced for sgutdown and system deployment
  3. Scan your main substation
  4. Integrating power cogeneration operation
  5. Integrate the existing load disposal system on demand
  6. Create an underfrequency and undervoltage charge disposal system
  7. Integrate your power factor control system
  8. Collecting data and reporting on SOE

Solutions Used and Equipment Provided

We use a multiprotocol data concentrator to enable communication with the different equipment and its communication interfaces.

A PLC with I/O cards that had event time-stamp was used to command and monitor cubicles, transformers, disconnectors and other plant equipment.

All logic of interlock and load disposal were implemented using this equipment in conjunction with intelligent relays that detected undervoltage and underfrequency.

To ensure the reliability of SOE (Sequence of Events) data, all equipment was synchronized via GPS.

Exhaustive platform tests have been carried out on the entire system to ensure fast and reliable deployment.
