Modelling and simulation of automatic generation control in power system / Tan Chang Hwa
Projek ini bertujuan untuk menjalankan pemodelan dan simulasi Kawalan Penjanaan Kuasa Automatik (AGC) dalam system kuasa yang terdiri dari pada kawasan penjanaan elektrik secara hidro dan haba yang sama dan bersambungan dengan mengambil kira kadar kekangan penjanaan dan turbin pemanasan semula. Prestas ikawalan penjanaan kuasa automatik yang mengaplikasikan pelbagai jenis alat kawalan di simulasikan dan di kaji dengan meletakkan 1% langkah beban pengusikan (SLP) di kawasan penjanaan elektrik secara haba. Alat kawalan yang diaplikasikan di dalam projek ini bagi menjalankan kawalan penjanaan kuasa automatic ialah kombinasi daripada alat kawalan P-I-D yang konvensional dan kombinasi antara alatk awalan PID yang konvensional dengan alat kawalan kecerdasan buatan Logik Kabur yang di gelar alat kawalan PID Logik Kabur. Alat kawalan kecerdasan buatan di gunakan dalam Kawalan Penjanaan Kuasa Automatik kerana prestasi alat kawalan konvensional menurun apabila kerumitan system meningkat tetapi alat kawalan kecerdasan buatan berprestasi baik dalam situasi ini. Justeru, projek ini bermatlama tmembuat pemodelan system kuasa hidro dan haba dan mendapatkan prestasi optimum alat kawalan. Parameter kedua-dua alat kawalan di optimumkan dengan menggunakan Teknik kamiran ralat kuasa dua (ISE) dan tindak balas di namik kedua-dua alat kawalan yang berada pada prestasi optimum di dapatkan dan di bandingkan. Daripada keputusan simulasi AGC, alat kawalan PID Teknik Kabur di dapati mempunyai prestasi dinamik kesuluruhan dan tindak balas fana yang lebih baik daripada alat kawalan PID yang konvensional sebanyak 25.29% dari segi indeks prestasi. _______________________________________________________________________________________________________ This project aims to model and simulate Automatic Generation Control (AGC) in the power system which consists of two equal interconnected hydro and thermal generating area, considering Generation Rate Constraint (GRC) and reheat turbine. The performance of the automatic generation control using different type of controllers is simulated and examined with a 1% step load perturbation (SLP) at the thermal generating area. The controllers being used in this project in order to perform automatic generation control are the combinations of the conventional P-I-D controllers and the combination of PID controller and Artificial Intelligence Fuzzy controller, namely Fuzzy PID controller. Artificial Intelligence controllers are being included in the study of AGC nowadays because as the system complexity increases, the performance of the conventional controllers tends to deteriorate but Artificial Intelligence controllers outperform conventional controllers in this situation. Therefore, this project aims to model the hydro and thermal power system and obtained the optimized performance by the controllers. The gains and parameter of the controllers are optimized using Integral Square Error (ISE) technique and the dynamic responses of the controllers at their optimal performance are determined and compared. From the simulation result of the AGC, it is observed that Fuzzy PID controller has better overall dynamic performance and transient response as much as 25.29% in terms of the performance index compared to the conventional PID controllers.
