Modernization of control system for link welding

kwadrat replacement of the old controller,

kwadrat replacement of electronics modules and replacement with a controller with a short cycle time,

kwadrat program processing (to control the spark welding process),

kwadrat replacement of the old power regulator supplying the welding transformer,

kwadrat replacement of the measurement system of the travel of the upset bracket,

kwadrat replacement of the visualization system,

kwadrat execution of a central SCADA station archiving selected parameters of each welded cell.

Scope of work:
 

kwadrat design,

kwadrat software,

kwadrat commissioning.

 

Used PLC controllers, terminals, communication, visualization systems:
 

kwadrat 1 S7-315-2 PN / DP central controller,

kwadrat 1 CX9020 Beckhoff technological controller to control the welding process,

kwadrat distributed structure of inputs / outputs on the site – 1 station on PROFINET in the operator’s panel,

kwadrat the AEG Thyro-A 1500 power controller with the PROFINET communication module,

kwadrat KP1200 graphic terminal,

kwadrat KP300 text terminal,

kwadrat PROFINET communication,

kwadrat 1 station with a database of selected parameters of each welded cell,

kwadrat remote access by connecting the controller to the factory Ethernet network.

List of controlled and measuring devices, control devices:
 

kwadrat 250 binary signals,

kwadrat 8 analog signals,

kwadrat 2 program PID controllers,

kwadrat 1 absolute wire draw encoder,

kwadrat 3 servo valves,

kwadrat 30 solenoid valves,

The project consisted of developing complicated software for PLC controllers in order to properly control the operating currents of the frequency converter.
Tests of the control system were executed (PLC + frequency converter software) on the customer’s test tower with a nominal load of 40 tons.
Two projects were completed for a total of 7 vessels. On each ship there were 4 mooring winches and 2 mooring and anchor winches.

Scope of work:
 

kwadrat design,

kwadrat prefabrication,

kwadrat software,

kwadrat commissioning.

Used PLC controllers, terminals, communication, visualization systems:
 

kwadrat PLC LS IS controllers, XGT series,

kwadrat HMI XP10 LS IS panel.

List of controlled and measuring devices, control devices:
 

kwadrat LS IS iS7 frequency converter,

kwadrat LS IS LV equipment

In 2015, 9 projects in the field of electrical installation were commenced at the construction of a new copper acquisition block at the KGHM steelworks in Głogów. Within the scope of the company’s work, all 9 projects were:
 

kwadrat assembly of cable routes,

kwadrat laying routes of power and control cables,

kwadrat performance of all required electrical measurements,

kwadrat connection and checking its’ correctness,

kwadrat start-up assistance

Scope of work:
 

kwadrat 9 projects – electrical installation works

The team implementing the projects numbered about 70 people. Works on this type of object are non-standard works, carried out at high altitudes. Power cables have been routed in previously prepared cable routes at a height of up to 60 m from ground level. It took one year and was successfully completed on time.
