Hardware and software system promHMI

Hardware and software system promHMI 9668

The software and hardware system PromHMI is designed to effectively organize the operational dispatch control of the substation in normal, emergency / post-emergency modes and dispatch control over the operation of equipment at the substation and adjacent electrical networks. We offer a full range of solutions and services from the supply of software and hardware for the creation of separate systems (PSCA, RPA, IATS) to the implementation of complex "turnkey" projects. The customer is given the opportunity to choose a technical solution for each specific project, depending on the characteristics of the object and its functional requirements, as well as advice on the design and implementation of the system, including on existing facilities.

Main functions of the PromHMI system:

  • collection and processing of analog and discrete information about the operating mode of the substation;
  • monitoring of the current mode and state of the main circuit of the substation from the dispatcher's workstation;
  • automatic control and regulation (freely programmable logic in the controllers of PromHMI system);
  • automated control of substation equipment;
  • recording of emergency events;
  • archiving and reporting;
  • hardware-software operational locks;
  • monitoring of the condition and operation of the main process equipment;
  • automation of auxiliary technological processes;
  • maintenance and synchronization of time;
  • technical accounting of electric power;
  • vector graphics, scaling, scrolling, automatic change in the level of detail of the circuit;
  • installation on the mnemonic scheme of warning and prohibitory messages;
  • monitor the status of RPA devices;
  • automatic reading of oscillograms from the RPA device;
  • display and processing of RPA triggering parameters (trip currents, local event viewing results);
  • ensuring information and general security.

Architecture of the software and hardware system рromHMI

    The architecture of the system consists of two parts:
  • 1. PromRTU controller, which directly collects data from RPA devices and other switching equipment at the substation using the existing Modbus RTU / TCP communication protocols, IEC 60870-5-101, IEC 60870-5-104, OPC and transmits data to the next level - ACS controller.
  • 2. ACS controller, which takes on the fulfillment of the main tasks of the automated control system:
    • conducts a survey of ACS controllers, collection, processing and storage of data;
    • works with the database;
    • transmits data to the upper level by various protocols (IEC 60870-5-101, IEC 60870-5-104, IEC 61850, OPC).

Main advantages of this system:

  • the ability to work on a single data transfer protocol;
  • no need for additional converters, adapters, media converters;
  • the overlay of timestamps for the polling frequency on the transmitted data directly from the controllers;
  • processing, data filtering, aperture for transferring changes directly to the dispatcher's computer, which reduces the load on the computer and reduces maintenance and upgrade costs due to no need to install a set of drivers for the final equipment of the aggregate level systems on the ACS controller;
  • possibility to add a backup storage to the ACS controller. In this case, the failure of the primary server does not lead to loss of control or shutdown of the production process.
This solution allows to refuse to purchase an expensive multitasking server operating system Windows, without increasing the hardware costs (dispatcher computer), allows you to divide the tasks of communication, saving and processing data between two promRTU and ACS controllers. The dispatcher computer does not need the additional software to be installed and increase the technical characteristics of the computer. All the load is borne by the ACS controller, which deals with laborious and resource-consuming tasks. This achieves the maximum possible speed in the interrogation of relay protection devices, and the processed data is immediately sent to the dispatcher computer.


  • Software of hardware system рromSCADA works under any operating system (Microsoft Windows, Linux, Mac OS).

The following protocols are supported:

  • IEC 60870-5-101;
  • IEC 60870-5-103;
  • IEC 60870-5-104;
  • DNP-3;
  • OPC;
  • IEC-61850;
  • IVCH.
Provides the possibility to keep the logs of the commands passing through the server, the error log and monitoring the signal values. The software management of the PromHMI hardware system is performed from the automated workstation of the dispatcher (AWS). Telemechanics utility of AWS is designed to view operational information from the ACS repository. A local archive of received data is provided to ensure continuity of the main archive on the database server.

  • installation on mnemonic schemes of messages by type: emergency, warning 1, warning 2, operational state;
  • maintaining lists of events and alarms with flexible filtering;

The main feature of the hardware and software system рromHMI that distinguishes it from the majority of foreign decisions and domestic developments, is that it can be shared with devices MP RPA of all domestic and foreign manufacturers, that provides support for a variety of standard communication protocols and flexible architecture of HSS. In all cases, the integration of RPA terminals is provided into APCS in its entirety, including the collection of information about start and operation, automatic reading of oscillograph recordings, control of RPA operating modes (operating input and output functions, and protection stages). Standard software from the manufacturer is used to view and change the settings.
