Abstract
Untuk mengetahui pengaruh kompensator statis pada kestabilan sistem daya dapat dilakukan dengan berbagai macam cara. Dalam penelitian ini, sistem disimulasi dengan memberi gangguan kecil kemudian dilihat responnya terhadap gangguan tersebut. Untuk membedakan adanya pengaruh kompensator, sistem lain yang tidak dilengkapi juga disimulasi dan dilihat responnya. Kedua respon dari masing-masing sistem kemudian dibandingkan. Respon yang dibandingkan di sini adalah perubahan sudut rotor, perubahan kecepatan putaran rotor terhadap waktu, dan perubahan tegangan dalam kompensator. Dari penelitian ini terlihat bahwa respon (perubahan sudut rotor) dari sistem yang dilengkapi kompensator menunjukan adanya redaman dengan penguatan SVC (Kv(SVC)) = 2.216 dan waktu kerja SVC (Tv(SVC)) = 0.01 detik. Sistem yang dilengkapi kompensator dengan kendali fuzzy logic dengan penguatan SVC (Kv(SVC)) = 0,4 respon redamannya lebih cepat selama 1 detik sudah teredam osilasi ± 2%. Nilai koefisien serempak dari sistem SVC negatif (Ks (SVC) = - 0,0029 torsi/rad per satuan) menunjukan kompensasi fasa mendahului (phase leading compensation). Perubahan sudut rotor semakin lama semakin mengecil. Sebaliknya, respon dari sistem yang tidak di lengkapi kompensator cenderung berosilasi terus. Pembahasan pada penelitian ini pada kompensator VSFC-SVC dengan metode Fuzzy Logic controller, sehingga mampu meningkatkan unjuk kerja VSFC-SVC. Kata kunci: VSFC-SVC, Fuzzy logic controller, eigenvalues, perubahan sudut rotor, perubahan kecepatan putaran rotor, dan perubahan tegangan dalam kompensator. To find out the effect of a static compensator on the stability of the power system can be done in various ways. In this study, the system is simulated by giving a small disturbance and then the response to the disorder is seen. To distinguish the influence of compensators, other systems that are not equipped are also simulated and viewed responses. The two responses from each system are then compared. The response compared here is the change in rotor angle, change in rotor rotation speed with time, and change in voltage in the compensator. From this study it can be seen that the response (change in rotor angle) of the system equipped with a compensator shows the attenuation of SVC (Kv (SVC)) = 2,216 and SVC (Tv (SVC)) working time = 0.01 seconds. A system equipped with a compensator with fuzzy logic control with SVC (Kv (SVC)) gain = 0.4 attenuation response faster for 1 second has been damped by ± 2% oscillation. The simultaneous coefficient value of the negative SVC system (Ks (SVC) = - 0.0029 torque / rad per unit) indicates phase leading compensation. Changes in the angle of the rotor increasingly smaller. Conversely, the response of an incomplete compensator system tends to oscillate continuously. The discussion in this study on the VSFC-SVC compensator with the Fuzzy Logic controller method, so as to improve the performance of VSFC-SVC. Keywords: VSFC-SVC, Fuzzy logic controller, eigenvalues, changes in rotor angle, changes in rotor rotation speed, and changes in voltage in the compensator.
