Abstract

Establishment of interconnection links between Process -Tank Loading electrical networks bring some advantages as there are excess capacity at Process which can be utilized in principle to feed Tank Loading. Some result of power system study will be as an input for operational purposes. Concerning Motor Starting Studies and Load Flow Studies and taking into account that the transformer is off load tap changing, the best tapping position for Isolation Transformer is at -5% (primary side).  The best technical power generation configuration is proposed with configuration 2 (two) Process -TEG and 1 (one) Tank Loading-TEG running with 2 (two) interconnection, provided with appropriate load shedding system. Bare in mind that during smooth power transfer from each Process-TEG which requires 3 (three) Process-TEG running in parallel, there is an issue on kA capacity of Process switchgear. Existing setting of protection relay shall be reviewed according to the result of protection coordination study

Abstract

Wind energy has become one of the most important and promising sources of renewable energy, which demands additional transmission capacity and better means of maintaining system reliability. The evolution of technology related to wind systems industry leaded to the development of a generation of variable speed wind turbines that present many advantages compared to the fixed speed wind turbines. These wind energy conversion systems are connected to the grid through Voltage Source Converters (VSC) to make variable speed operation possible. The studied system here is a variable speed wind generation system based on Doubly Fed Induction Generator (DFIG). The rotor side converter (RSC) usually provides active and reactive power control of the machine while the grid-side converter (GSC) keeps the voltage of the DC-link constant. The additional freedom of reactive power generation by the GSC is usually not used due to the fact that it is more preferable to do so using the RSC. However, within the available current capacity the GSC can be controlled to participate in reactive power generation in steady state as well as during low voltage periods. The GSC can supply the required reactive current very quickly while the RSC passes the current through the machine resulting in a delay. Both converters can be temporarily overloaded, so the DFIG is able to provide a considerable contribution to grid voltage support during short circuit periods. This report deals with the introduction of DFIG,AC/DC/AC converter control and finally the SIMULINK/MATLAB simulation for isolated Induction generator as well as for grid connected Doubly Fed Induction Generator and corresponding results and waveforms are displayed.

Abstract

The application of sliding mode techniques the position control of a brushless servo motor is discussed. Such control laws are well suited for electric power inverter. However, high frequency commutations are avoided due to the mechanical systems. Various recent schemes are studied and operated to derive control solutions which are technically feasible. In spite of straightforward applications the resulting systems show robust performances to parametric variations and disturbances. Robustness studied with respect to rotor flux uncertainties and to stator resistance which varies with the temperature of the motor.

Abstract

Setelah 70 tahun merdeka dan rapuh dalam ketahanan energi, kita perlu menata kembali sektor dan industria Hulu Migas. Disatu sisi kedaulatan pengelolaan sumber daya alam dipermasalahkan kesesuainnya dengan konstistusi, di pihak lain impor minyak dan BBM dibiarkan terus meningkat. Padahal seluruh impor berasal dari sumber yang dikuasai asing. Bentuk Satuan Kerja Hulu Migas menjadi tidak sesuai untuk pengelolaan Migas, karena untuk menjadi Badan Usaha harus mempunyai keuntungan dan keuntungan dari hasil pembagian produksi migas yang menjadi profit SKK Migas tidak cukup menjadikannya sebagai badan usaha. Jika prediksi produksi dan cadangan migas Indonesia yang semakin menurun maka bila tidak ada eksplorasi yang baru, SKK Migas ini akan membukukan keuntungan yang terus menurun sesuai dengan trend produksi. Sementara, seperti halnya Badan usaha yang lain, expense perusahaan akan terus naik dari tahun ke tahunnya. Pengelolaan Migas yang sesuai untuk Indonesia adalah mengembalikan fungsi pengawasan dan Pengelolaan Migas ini kepada Pertamina sehingga akan memaksimalkan keuntungan buat negara dan hasil migas akan dapat dinikmati oleh daerah penghasil migas.

Abstract

Koordinasi proteksi adalah pemilihan alat pelindung dan penentuan setelan waktu guna menentukan daerah perlindungannya terhadap gangguan sementara dan mengkoordinasikan alat-alat perlindungan. Manfaat koordinasi alat perlindungan adalah meminimumkan daerah atau bagian yang terganggu dan menentukan tempat terjadinya gangguan. Hasil akhir dari analisa koordinasi proteksi adalah gambaran tentang bagaimana koordinasi antara circuit breaker pada jaringan sisi atas (upstream) dengan circuit breaker pada jaringan sisi bawahnya (downstream). Setiap motor bekerja pasti memerlukan suatu peralatan pengaman untuk mencegah terjadinya gangguan pada sistem. Circuit breaker adalah alat proteksi yang bekerja untuk memutuskan sirkuit saat terjadi gangguan. Ada beberapa circuit breaker yang terpasang pada instalasi motor yang saling berkoordinasi membentuk diskriminasi, agar pada saat terjadi gangguan hanya pada circuit breaker yang mengalami gangguan saja yang trip sedangkan yang lainnya tetap beroperasi. Program ecodial merupakan program yang digunakan untuk mengetahui apakah terjadi diskriminasi atau tidak. Hasil yang didapat dari program ecodial adalah circuit breaker pada bagian sumber dan circuit breaker pada bagian MDP terjadi diskriminasi total. circuit breaker pada SDP dengan circuit breaker pada bagian motor juga mengalami diskriminasi total, hanya pada circuit breaker PP 5, 10, dan 11 dengan SDP 5, 10, dan 11 tidak mengalami diskriminasi.

Abstract

Penalaan parameter kontroller PID selalu didasari atas tinjauan terhadap karakteristik yang diatur (Plant). Dengan demikian betapapun rumitnya suatu plant, perilaku plant tersebut harus diketahui terlebih dahulu sebelum penalaan parameter PID itu dilakukan. Karena penyusunan model matematik plant tidak mudah, maka dikembangkan suatu metode eksperimental. Metode ini didasarkan pada reaksi plant yang dikenai suatu perubahan. Dengan menggunakan metode itu model matematik perilaku plant tidak diperlukan lagi, karena dengan menggunakan data yang berupa kurva keluaran, penalaan kontroler PID telah dapat dilakukan. Penalaan bertujuan untuk mendapatkan kinerja sistem sesuai spesifikasi perancanganKata Kunci : Simulasi; Tuning PID; PID Controller; Pengendali Proses
