The following items belong to power supply systems:
Linear nets and junctions devices of power units
Power supply systems for various companies
Junction gears for power consumers
For the above mentioned facilities we can offer development (upgrade) and introduction of the following system for automation of monitoring and metering:
ASKOUE - automated system for power supply control and routine metering
ASDOUE - automated system for power supply monitoring and routine metering
ASKUE - automated systems for power commercial metering
ASKOUE systems are aimed for routine monitoring of power supply and technical metering of power consumption in power supply systems of various companies.
ASKUE systems are aimed for automation of IT support for calculations of payments for consumed power between the supplier and consumer.
ASKUE has the following functions:
Central routine monitoring of power supply and power consumption
Current state of operation system (state of switching equipment of the main power supply), current values of main parameters for power consumption (load current, voltage, power demand, cos φ etc.) and state of protection devices and local automatic devices.
Warning and emergency alarm
Monitoring of power supply and power consumption
Follow up and archiving monitoring results for the operation scheme and power consumption metering
Follow-up and archiving monitoring results of operation (actuation) of protection devices and local automatic devices
Follow up and archiving of actions by operating personnel and managers
Automatic generation of reports
Providing specialists with various tools to analyze power supply and consumption - graphics, automatic search of extremes and critical situations etc.
Recording consumed power (active/reactive) as regards inputs and connected consumers; for ASKUE - commercial metering in compliance with the market status of the system
Generating balance sheets for parts and sections of monitoring and metering
Calculation of technical and economic rates
Informational and physical protection from unauthorized access to the system resources
Supervisory control (remote control)
Oscillographic testing, monitoring and quality analysis (coefficients of current and voltage anhormonicity, harmonics coefficients, frequency deviations etc).
Standard scope of monitoring and metering for each connection:
Positioning of switching devices
Voltage (phase and linear) for each phase and average
Current, for each phase and average
Active capacity, for each phase and total
Reactive capacity, for each phase and total
Full power, for each phase and total
State of protection devices and local automatics
Development and Introduction
Structure of control points and metering, balance sheets, functions and technical parameters are developed during pre-engineering evaluation and development of technical assignment as per technical provisions from power supplying companies, regulatory documents, distribution structure of GPP, TP, RU, KTP and KPU, requests and opportunities of the Customer.
The systems are based on the most advanced technical means:
FOL, radio channels
equipment and software by the leading companies in the sphere of power supply and IT integration - Schneider Electric, ABB, SIEMENS etc.
Ethernet TCP/IP and Web- technology
Products by SME Tomsk Electronic Company (NKU, BUZ etc.)
Instruments (sensors) are selected basing on Customer's request regarding scope and metrological parameters. Also one considers market status of generated system and metrological parameters used for the system of primary transducers to be automated - current transformers, voltage transformers etc.
Integrated solutions from SME Tomsk Electronic Company allow integration into supplementary control systems - gas detection, lubricating system control, local control devices and overloading protection etc.
