Technical Description
The main Spreader Power Supply 35kV is realized by trailing cable (with optical fibers) wound on the console cable drum with slip rings for connecting MV Switchgear power supply cables.
The basic concept for placement of electrical equipment is in E-houses (containers) on Spreader’s superstructure, substructure, intermediate unit, tripper car unit. Two operator’s cabins at the receiving and discharging boom, with ergonomic design, meet the line of sight requirement for the operator.
Belt drives, traveling drives and Discharge Boom Hoist Winch drive are powered and controlled by frequency converter system ’multi drive’, with 12-pulse rectifier with chopper and brake resistor.
The control system of the Spreader is realized with PLC and distributed I/O units. A redundant network structure is applied in optical fiber level. An uninterruptible power supply (UPS) is installed to provide, in case of failure, proper shut down of the control system.

Automatisierung des Wiege- und Gießsystems für Kupferanoden in der Kupfermine Bor
The customer request was to provide refurbishment of the control system for liquid copper casting “machine”, which is at the end of the copper producing technology chain. Liquid purified copper (98%, after Pierce Smith converters) flows from the anode furnace through ladle mechanism, where the material is weighed. After casting the round cast table automatically turns to the lifting and horizontal transfer system. Mold capacity is 0,5t. In order to produce the anode plates of a particular shape, the allowable weighing fluctuation is ±2%. The whole casting cycle takes 36 sec (filling, weighing, emptying).
 
Scope of Work
Mikro Kontrol provided detailed and as-built design, weighing system reconstruction, drive system reconstruction, MCC and control panel manufacturing (including operator panel), application software, supervision of the electrical works at the site, as well as testing and commissioning.
Benefits
  • State-of-the Art equipment and solution; the old machine was out of work for several years
  • Increasing production capacity and product quality
  • Maximum level of reliability and availability
  • Operation and maintenance convenience
  • The whole project is done within 6 months. It’s successful realization encourages customer to plan the modernization of the second casting machine.
Technical Description
The two DC drives for round cast table positioning are substituted with AC electromotor drives coupled to the same reduction gear and controlled by a “multi-drive” frequency inverter (master – follower mode). Replacement of old AC drives for the copper plate lifting mechanism is done with new AC motor-gear drives, with frequency inverters parameterized for hoisting applications.
Instead of the old weighing system, the new Load cells and measuring amplifiers are installed. The control of the filling and emptying process is realized through proportional hydraulic valves.
The positioning of the round table and it’s movement control are based on absolute encoder and a system of binary sensors mounted on table’s construction.
The control is realized by the PLC in control cabinet in electric room where MCC and LV panels are installed. The PLC is the part of the Smelter and Refinery DCS control network.
Operator control is realized with HMI and control desk mounted at the operator room location.

Scope of Work
Mikro Kontrol provided detailed and as-built design (MCC, DCS, network), application software, supervision of the electrical works at the site, as well as testing and commissioning.

Benefits
  • Implemented DCS equipment and solution
  • Maximum level of reliability and availability (24h / 7 days)
  • Well-tuned process parameters
  • Operation and maintenance convenience
  • Project fully done within 6 months
Technical Description
The control and monitoring scope of DCS involves:
  • 29 motor-actuated and hydraulic-activated valves
  • 17 frequency-driven pumps
  • 28 process transmitters
  • 15 regulating loops (standard and cascade PID implemented)
  • 7 energy-calculating devices on fieldbus
The operator station network includes two redundancy servers and five client computers (two standard and three with touch screen displays for local monitoring of control system of new boilers).
Mikro Kontrol integrated into DCS control network control subsystems from different manufacturers: Weishaupt (old boilers) and Oilon Burner Management System BMS (for the new boilers).
Local control of the boiler and BMS devices is realized with touch screen display computer as the client station; this asked programming modification of original DCS libraries, since such approach is not supported by DCS.
Energy efficiency and environment protection are realized by the well-tuned regulation loops and Continious Monitoring of Flue Gas Emission (CEMS) integration within DCS.

Modernisierung von zwei Portalkranen 160/50 t, HE PP Djerdap
Mikro Kontrol did a full reconstruction and modernization of two gantry cranes, capacity of 160/50t to support hydro-mechanical equipment in individual work as well as in coupled work.

Scope of Work
Existing wound rotor motors are replaced by corresponding induction motors with squirrel cage rotor. The speed and torque are now regulated by an energy recovery multidrive frequency converter.
Control supervision of each crane is performed by a distributed PLC with appropriate operator panel, located in the operator cab. Coupled work of both cranes encompasses the load distribution in order to equalize the speed of the same drives of each crane.
 
Benefits
  • Reliable work in both single and coupled mode
  • No portal corruption
  • The supervision and control of the load amount of each hook
  • Safety circuit implemented
  • Monitoring alarm system
  • The speed limit in relation to the position and load management driving portal in terms of drive synchronization on both sides
 
Technical Description
Installation of a new cable trolley provided reliable power supplies for energy recovery multidrive frequency converter, located on each crane. Thanks to use of these energy recovery frequency converters Mikro Kontrol increased the energy efficiency of the system.
When in a coupled mode, both PLCs connect with each other through the network by a wireless connection. In this mode one PLC is master and another is slave. This configuration enabled the possibility of a single control point, either a cab or a remote control unit of the master crane.
