ABSTRACT DYNAMIC SECURITY LEVEL ASSESSMENT OF SPECIAL PROTECTION SYSTEM (SPS) IMPLEMENTATION USING FUZZY TECHNIQUES: STUDY CASE BANGKA-SUMATERA INTERCONNECTED SYSTEM By INDAH PERMATA SARI NIM: 23220096 (Master’s Program in Electrical Engineering) This thesis study will be focused on efforts to increase the reliability of the Bangka Electricity System, namely by designing the interconnection of the Bangka system with another system that is stronger and has a better energy mix, Sumatra System. This research will analyze the implementation of the Special Protection System (SPS) Event-Based and Parameter-Based as a new defense scheme by taking corrective actions to keep the system stable and reliable. These actions include tripping generators, loads, and reconfiguring the system automatically and quickly. The performance of this SPS will be tested on 10 contingency events with four different load profiles and the system response will be observed in terms of frequency stability, voltage and rotor angle. From the research results, it can be concluded that the SPS performance on the Bangka-Sumatra Interconnection System has a better and more effective performance than the existing defense scheme, as evidenced by the results of dynamic security assessment (DSA) testing using Fuzzy Techniques.
