Grid Connection Study for HPP Janjici

HPP Janjici (16.6 MW) is currently in the designing phase, planned to be commissioned in 2024.

One of the basic goals of this Study is to suggest necessary conditions for connection of the new HPP to the power system, for the given plant location and assumed operating conditions of the power system. The other goal of the Study is to determine electromechanical characteristics and parameters of control systems of the new power plant for the expected conditions of the power system, as well as parameters of step-up transformers. All suggested parameters and characteristics must be in line with the security criterions. Calculation results should point out increase of short-circuit currents and its effects to equipment within zone of influence of the new power plant.

Type of services provided:

• Checking of relevant parameters and characteristic of the new generation units and their step-up transformers
• Load flow and voltage profile analyses
• Security analyses
• Short circuit analyses according to IEC 60909
• Static and Transient stability analyses
• Auxiliary supply assessment
• Selection and verification of electromechanical parameters
