Designing
We carry out design and construction documentation in the following sections:
AK – automation and control of production processes;
EM – power electrical equipment, networks 0.4 kV;
EO - electric lighting;
Designing can be one- or two-stage.
One-stage project: RP stage (working project)
Two-stage project: stage P (project), stage P (working documentation)
All our projects are carried out in accordance with the norms and rules of DBN and PUE, comply with DSTU and ISO standards.
When developing CHP projects, we use the European equipment classification and coding system KKS (Kraftwerk-Kennzeichensystem).
The main software we use for design is EPLAN Software & Service GmbH & Co., SolidWorks, and Autodesk Autocad.
The main modules of the EPLAN platform that we use
• EPLAN Electric P8 — modular and scalable solution for electrical engineering design, automatic creation of design and working documentation. • EPLAN Fluid — software for designing pneumatic/hydraulic automation, lubrication and cooling systems and automatic creation of corresponding design and working documentation. • EPLAN ProPanel — 3D design of electrical cabinets with data transfer to production. Virtual three-dimensional modeling, creation of two- and three-dimensional drawings, three-dimensional image of wiring and routing diagrams, availability of templates for drilling equipment operation and integration with CNC machines. • EPLAN FieldSys — work with route plans. • EPLAN PrePlanning — software for preliminary (sketch) design of objects and generation of design documentation. Used to create functional automation diagrams.
Principles used in the construction of the PCS
• PCS is a PTC consisting of sensors, actuators, controllers, servers, operator workstations, active and passive equipment of the local computer network, as well as standard basic and application software used to create modern distributed control systems. • The control and automation system is usually distributed and multi-level. It provides for parameter control using converters and secondary devices installed on the KVP and A panels, as well as operator's ARMs (automated workplaces). • Level 1 - "Field" (sensors, converters and actuators installed in place near the equipment); • Level 2 - "Lower" (PLC installed in a switchboard with air conditioning; remote distributed input-output stations, which can also be installed in place near the equipment, in order to save on cable and wire products; frequency converters, operator touch panels). As PLC we use controllers from well-known manufacturers: Siemens, Schneider, ABB. Operator panels Siemens, Delta Electronics; • Level 3 – “Upper” (a client-server structure can be used (duplicated servers installed in the server rack and operator ARMs installed in the main operator room), and separate workstations (standalone) can be used. • Simatic WinCC Professional as part of “TIA PORTAL” is used as the upper-level SCADA program. It is also possible to connect to the Internet, which allows you to monitor the station processes remotely, via a web interface or the “WinCC Webnavigator” software product. • The software of the controller and upper-level system provides the ability to develop, modify and debug programs in both OFF-LINE and ON-LINE modes, i.e. without interrupting the operation of the functioning system. • The PTC provides for redundancy of the lower and upper-level networks. The main lower-level network usually has the “Profinet” data transfer protocol, data transfer rate of 100Mbps, copper cable, ring network topology from device to device. When the distance between distributed I/O stations is more than 100m, an optical data transmission medium is used. The upper-level network is usually built on the basis of Ethernet with a data transfer rate of 1000Mbps and is implemented using industrial switches with network redundancy. The topology is mixed: ring and star. The switches are powered by a redundant power source (two independent inputs with an automatic switching scheme and power supply via UPS). • Upon agreement with the customer, frequency converters with a hybrid control scheme can be used in the automation system to reduce the number of cable products: via the PROFINET network and in the event of its complete failure - control by discrete signals. • Automatic regulation, protection and blocking are implemented at the PLC level and in the event of a complete loss of communication with the workstations - they always remain in operation. • Control of actuators is possible both manually on site and remotely from the workstation or automatically according to programmed algorithms. • To enable local control of some equipment and to increase the reliability of the system (in case of loss of control through ARMs), touch control panels are used. • When designing the PTC, the principle of standardization and unification is applied, which consists in the rational use of typical, similar, unified and standard circuit solutions, designs and equipment components. • When designing, the required number of input/output channels and backup channels is provided for, not less than 10% for each type of signal. • PTC equipment is placed in industrial electrical cabinets with a protection level of not lower than IP54.
