HMV Engineers has developed Digital Substation Solutions, innovating through the implementation of control and protection systems based on hardware and software in accordance with the IEC 61850 standard; and in the last few years has been working on implementing the process bus according to IEC 61850-9-2LE and IEC61850-9-1 as innovative solutions in a field that has not been explored in Latin America and pioneering in Colombia.In collaboration with the areas of electromechanical, civil engineering and construction services of HMV Egineers, integral projects can be supplied and built that reflect the benefits in terms of cost, civil works reduction and execution times offered by the process bus technology.These solutions are based on the collection of all analog and digital signals from the patio equipment to a digital information acquisition unit adjacent to them, which is interconnected to the control and protection panels in the control building, through an optical fiber. For each solution designed and implemented, an extensive testing process of stability, reliability and effectiveness is carried out.The solutions developed combine the use of equipment with different operating principles and also from different manufacturers, always in line with the recommendations of the IEC61850 standard, which defines communications standards for equipment in substations.
