Kalkitech’s Power Systems Group has vast experience in understanding and meeting the various needs of a power system. A snapshot of some of the key projects completed by Kalkitech is given for your reference.

  • Power System Studies for  a steel plant in the Middle East

Power system studies include load flow analysis, short circuit analysis, motor starting studies, harmonic analysis, protection studies and relay setting studies. The system had an electric arc furnace, a ladle furnace, an SVC, 6.6 plant, several 415 volts switch boards supplying LT loads.

  • Transient Stability Simulation Package for a public T&D utility 

The transmission network is a three phase balanced network system which is interconnected with another SAARC nation grid. The project required a transient stability analysis module in three phase systems for evaluation of the electro-mechanical transient response of the system. The client wanted the transient stability analysis module to fetch the data from EMS/SCADA, perform analysis at specified intervals of time, and add specific types of events to the transient stability simulation to cause transients [or disturbances or events] in the network.

  • Power Plant related Studies for a multinational consulting & engineering company

The project included reinforcement of an existing power plant with two additional gas turbine generators with 132 kV grid interconnection and plant auxiliaries represented completely. The scope included load flow studies, short circuit studies as well as protection and coordination.

  • Power Evacuation Scheme for a multi-national manufacturing company

The client’s captive power plant generated surplus power and the client wanted to conduct Power Evacuation Studies to export power to external bulk consumers and T&D consumers. The scope of the work included  site visit, site survey, examination of facilities available, meeting with the T&D  system authorities as well as nearby bulk power consumers and performing various short-term/long term power system studies like load flow studies, short circuit studies, harmonic analysis, stability studies, protection coordination studies, insulation coordination studies as per relevant IEC standards.

  • Protection Coordination Study for a Water Treatment plant

Kalkitech’s power systems experts performed protective device co-ordination analysis for HV panels including two HV incomer panel, two 16 MVA, 33 kV/6.9 kV power transformer, one bus coupler, eight +1 spare distribution transformers ( including LV side breaker of the transformers ),  five +1 spare motor feeders etc and provided results  and recommendations as required by the specifications and the client.

  • Power Systems Training for a multi-national company in Middle East 

The Power System Group (PSG) at Kalkitech successfully provided power systems training to utility engineers in a Middle East country. Experts from PSG prepared the syllabus, tutorial notes, and conducted a five day course at the client site. About 20 engineers from different utilities in the Middle East participated in the training program.
