Hardware and software system promHMI

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.

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.
