Automation of technological processes
The complex approach to the decision of problems Technological Process Automatic Control System - our major principle.
Systems developed by us are as much as possible approached to requirements of the customer.
That considerably reduces time of development of system the operational personnel.
Created graphic screens SCADA of system always are evident, Are informative, simple and clear to attendants.
Used programs of visualisation are compatible to Windows applications
that facilitates integration In existing information control systems of the enterprise.
We develop and we introduce systems of different architecture,
the sizes and complexity and We unite the equipment of various manufacturers, at level of controlling metres,
SCADA-systems, controllers and drives. Testing of systems before introduction on manufacture with Use of mathematical models allows
to adjust key parametres and to check work Programmno-technical part, that considerably reduces terms of input of the equipment in operation.
As a part of RVSA, Ltd there is the department of the drive which is engaged in working out and a heading of designs, connected with electric drives and control systems of any appointment and complexity. The big engineering potential and serious technical training allows our employees to solve practically all problems in the field of the drive.
Use of new production engineering in management of the electric drives, based on microprocessor management, provides completeness of implementation of tasks in view in the field of the controlled-velocity electric drive.
The complex approach to working out helps to generate sweepingly and accurately demands to systems of electric drives and by that to devide out a time of implementation of the design.
“RVSA”, Ltd. carries out project development of aggregate control system of different technological processes not
only newly-implemented but also their modernization and reconstruction.
Total volume of project execution:
- Object examination to define necessity and sufficiency of modernization required.
- Providing to the customer with the draft proposal relying on optimum price, effectiveness, quality and reliability of system and equipments relations.
- Execution of technical and detailed engineering with program development for control systems with programmable logic controllers (PLC), programming of control AC and DC drive units with microprocessor control systems, development viewers and diagnostic devices on the basis of SCADA system.
- Selection and supply of required equipment of leading companies specialized in automation, electric drive and electric power supply areas.
- Production of optional equipment, complete devices and control cabinets by motors and actuating units (MCC).
- Equipment installation or supervision installation at site.
Recently the operations approach on reconstruction project implementation was changed.
Currently approach to revamp projects has changed.If designing works, equipment supply, commissioning and
installation were usually carried out by different contractors before, a client requires integrated approach to the work now,
which is called “ready-to-operate”. Because of these requirements “RVSA”, Ltd., has either partner’s agreements with
Kazakhstan leading electric installation firm (“Kazelektromontazh”, Ltd., “SAEM Centre”, Ltd.)
or their own installation area for carrying out any difficult installation work.
One of the biggest works, carried out by our enterprise recently is the sixth line reconstruction for
the cement production with dry process at “Karcement”, Ltd., Karaganda region, Aktau. At this object we had carried out as follows:
We carried out installation work according to the
Our specialists carried out design, instillation and adjustment works, which aren’t enter in the main reconstruction project.
- old cable production dismounting;
- cable steel construction dismounting;
- power transformers 110/35 kV dismounting;
- high voltage compartments and PCU dismounting;
- manufacturing and installation of steel constructions, supports, trays and ductings;
- Switchgear and control gear 35 and 10 kv Installation of the firm ABB;
- Installation of high voltage cable lines 110, 35,10kV;
- power transformers 110/35 kV 40 MBA installation of the firm ABB;
- motor installation 10kV;
- checking and optical cable lines installation;
- installation of electric equipment and cable lines 0,4 - 0,66 kV;
- Installation of instruments and automatic equipment.
Reconstruction of electric equipment and control system for the grinding shop No2 of “Karcement”, Ltd.,
and the compressor station “CentralAsiaCement”, Ltd. Was carried out by “RVSA” in volume: designing, equipment supply,
installation and commissioning.
“RVSA” specialists were carried out the project of automatic control and protection systems with
equipment using during the boiler No11 reconstruction of Karaganda state district power plant-1.
Also electrical installation was carried out by our staff.
