Our system is based on the most up to date IT solutions. At the same time, PowerVizor is a modular system that can use already existing IT systems and components at a customer side.
The Technological Monitoring module consists of the following subsystems: Boiler, Turbine, Own needs, Heating, AMR system, Chemical water treatment and others, for displaying the current operational state of equipment, technical and technological parameters of the station, with the possibility to display them on graphs and transfer them to the Measurement Analysis module. This will allow real-time displaying operating boilers and turbo units, high-pressure heaterы, boilers, feed electric pumps and the main parameters of their operating modes: consumption, temperature, steam pressure, electrical and heat load, water consumption, fuel saving reserve in case of deviation from the nominal value, etc.
The program interface will display in graphical and tabular form the actual performance of the equipment for each hour, day, month, as well as the planned indicators and standards.
The Databases subsystem is built on the basis of modern real-time DBMS and provides.
Centralized processing, storage and automated analysis of data, as well as a unified, simple and convenient system for displaying information constitute together a powerful tool for analyzing the technical, technological, economic condition of individual equipment, as well as of the power unit and CHPP in general.
Access to data is provided only to authorized users, taking into account their official powers, as well as the category of the requested information.
The system includes a specialized backup and data recovery subsystem.
The security and configuration subsystem ensures a high level of safety and comfort for users with the PowerVizor AIS.
The subsystem allows restoring the functioning of the AIS with a correct restart of the hardware with automatic backup of the system data by means of the system and basic software (OS, DBMS).
The subsystem ensures the safety of all available information in case of accidents, and in the absence of communication between the AIS and the enterprise server (communication subsystem with the cloud), the system forms a backup archive of the station operation data, which is transferred to PowerVizor after the communication is restored.
The Analysis of the Personnel Work module is intended both for automatic calculating and analysis of the equipment operating modes, and for assessing the effectiveness and correctness of the decisions made by the operating staff of the station.
The module includes the following composite forms of initial data and design parameters of equipment and staff:
The algorithm implemented by the module according to the regime maps determines the optimal design parameters of the boilers (97 parameters) and generates tasks and constraints on the physical parameters. In real time, the operating modes of the boilers are monitored and the deviation of the actual indicators from the calculated ones is analyzed with automatic determination of penalty points for staff, in case of violations of the optimal operating modes of the equipment. The result in the form of tables with deviation values, as well as calculated values of penalty points for operating staff for any analyzed period (for example, for a shift or a month). Awareness by the CHPP’s operating staff of continuous recording of all modes and actions is an incentive and increases the culture of production and the personal responsibility of each employee.
This module allows determining both the equipment operating time and the amount of time the boilers have been operating in non-optimal modes.
The Energy Market Order module is a convenient tool for quick and accurate formation of requests for the wholesale electricity market: Day-Ahead Market and Intraday Market, as well as distribution of the load between the power units based on the trading results received from the Market Operator, which makes it possible to significantly simplify and facilitate the work of both the operating staff, the Production Technology Department, and the Commercial Department of the station. The analytical tools implemented in the application make it possible to efficiently interact with the Market Operator and optimally manage the distribution of power between the generating units of the station. The module allows you to achieve maximum efficiency of the station in the wholesale electricity and capacity market.
The Technical and Economic Indicators module allows performing on-line calculations and predictive analytics:
The TEI module implements a multi-user mode of operation in reporting forms with different time periods, up to an hour, and with different restrictions (technological, technical, economic). It implements the possibility to accumulate and save the provided data for enterprise users..
The TEI module takes into account all the features of the station related to its topology, instrumentation pool, technical condition of the main and auxiliary equipment. The calculation algorithm allows to be flexibly adapted to changes in technological or technical parameters due to the possibility of changing the parameters and coefficients of the calculation formulas.
The toolkit of the TEI module provides advanced functionality for reducing labor costs for calculating and accounting TEI, minimizing the share of manual labor and, as a result, the number of errors, increasing productivity, accuracy and detailing of calculations.
The system in general and the TEI module in particular are compatible with the existing TEI databases and archives, calculation algorithms, reporting forms, regulatory reference and other information. It allows to automatically download data on technical and commercial accounting in real time from various sources (AMR, ACS) and configure an unlimited number of calculations and reports.
The algorithm of the TEI module and the system in general has a high fault tolerance and ensures the safety and consistency of data.
The Measurement Analysis module allows for a detailed analysis of both individual technical or technological parameters and the efficiency of the equipment or station in general.
The module allows you to analyse the operating modes, accounting of fuel costs for energy generation, accounting of station losses and balance. It also allows identifying bottlenecks in the operation of a station or individual systems, diagnose and localize symptoms, formalize and structure the causes and results of decisions.
The Load Calculator module implements the following functions.
Determination and real-time display in one coordinate system of the enterprise energy indicator values in the form of the following dashboards:
Automatic finding of the optimal parameters of the generated power. Preparation of data and support for decision-making for work on the wholesale electricity market.
Accounting for resource consumption for technological needs, heat and electricity losses.
Submission of data on the current efficiency of the power unit and its individual elements to the calculation group of the Production Technology Department, which makes it possible to correct the modes and predict the timing of equipment withdrawal for repair.
The module allows forming a task (command) for changing the supply in general for the station and changes for individual power units, both in the balancing market and market for additional services for a certain period, taking into account operational safety. Moreover, the number of tasks (teams) can be unlimited.
The Power Unit Status Calendar module works in conjunction with the modules Assessment of the drivers’ work and Measurement Analysis and forms both anachronistic, operational and predictive analytics for the operation of individual units, systems and power units in general.
The module takes into account the operation of equipment both in an underloaded state and with overloads. Current and planned repairs, emergency shutdowns and putting into reserve etc. are also taken into account. A logbook is kept for recording the operation of the enterprise equipment.
