The following Course Conclusion Work II Positive Sequence Voltage (TSP) efficiency exam. Compared to other disturbances common in power distribution systems, it is used to detect and distinguish conductor breaks and other system events such as: capacitor bank switching, distributed load switching, centralized load switching, side branch switching and tension disorders. In addition to reducing the implementation and maintenance costs of the distribution equipment used in the energy distribution system, the planned method is simple and practical to be implemented in the energy distribution system. The power distribution systems used for the tests are the 5-bus, 33-bus, and IEEE 34-bus system test feeders. To verify the method's performance, it was used in the computer simulation program ATPDraw to test and extract the voltage signal characteristics. Then, through the Octave software, white Gaussian noise was added to the three-phase signal, to test whether the method is considered noise proof. Afterwards, the signal was filtered by a second-order Butterworth filter with a cut-off frequency of 180 Hz. After that, the filtered three-phase voltages Va, Vb and Vc are windowed in each cycle (γ) and a sampling rate of 128 samples per cycle. Next, the Fast Fourier Transform is used to calculate the phasor. Finally, in order to reach the minimum number of equipment deployed in the distribution system, which allows for the reduction of the system's operating costs, it is implemented in the GAMS software, which allows optimizing the best voltage points in the system. The results show that detection of conductive breaks through the TSP is effective and distinguishes it from other system events, therefore, an efficient, accurate, robust and reliable method is made to help correct interferences in the electrical system and provide more reliability and quality to energy distribution systems. The work will continue to apply the same method to other power distribution systems with different topologies and characteristics to verify the effectiveness of the proposed method.
