Implementation of Simulation of Possible Short Circuit Fault Situations in Wind Energy Plants By Power Analysis Program
Öz
The primary mission of electrical equipment in power systems is to provide life and property safety, and then to ensure uninterrupted and quality energy flow. Therefore, in order to ensure the continuity of an uninterrupted and quality energy flow while designing power plants, it is very important to determine the possible malfunction situations that may occur in energy systems and to calculate the minimum and maximum values of short circuit currents that may occur in the power system for the possible error situations. In order to prevent the energy flow from being interrupted in the system, it is necessary to detect every kind of malfunctions that may occur in the network beforehand, to isolate them from the system or to limit the value of short-circuit currents that may occur in the power flow system to a specified level in case of a malfunction. A generator connected to the medium voltage network is preferred to have neutral grounding so that it does not suddenly switch to island mode. The electrical connection type of the network in renewable power plants has a significant effect on limiting the value of the short circuit current that will occur in case of the most common phase-to-ground short circuit fault in these systems. Neutral grounding that must be done in the system in order to prevent the short circuit current that will occur in case of faults that may occur at weak points of insulation in the system from reaching very dangerous dimensions, ensures that the phase-to-ground fault condition is detected and the value of the fault current that will occur as a result of a short circuit is taken under control. In power flow systems, the grounding system must be selected in accordance with the power flow system to perform these two functions. In this context, a wind power plant consisting of seven wind turbines was first electrically modeled in a power simulation program. Then, possible fault scenarios of the power plant were tried to be determined on the obtained electrical modeling circuit. In case of a short circuit for the detected fault scenarios, the necessary analyzes were made on the system, solutions were presented for the most common phase-to-ground short circuit fault situation in practice with 70% and the value of the fault current was tried to be limited at certain levels. YNyn transformer connection status and 20-ohm ground resistance value obtained in the study were found to form the lowest phase-to-ground short circuit current status.
