Pembelajaran praktikum sangat dibutuhkan oleh mahasiswa agar dapat menerapkan dan mengintegrasikan pengetahuan serta keterampilan khusus yang telah dimiliki juga sebagai sarana untuk membuktikan teori secara ilmiah. Praktikum pengukuran power factor (pf) salah satu yang penting bagi mahasiswa program studi teknik elektro konsentrasi power system. Permasalahan timbul karena sejak pandemi, mahasiswa dibatasi bahkan dilarang untuk berkegiatan di kampus termasuk bengkel dan laboratorium. Solusi yang diusulkan adalah merancang model praktikum simulasi pengukuran pf menggunakan software Matlab/Simulink. Model praktikum harus dapat menggambarkan parameter system jaringan yang sesuai dengan praktikum laboratorium sehingga mahasiswa benar-benar dapat menerapkan dan membuktikan teori serta pengetahuan yang telah didapat. Hasil rancangan menunjukkan bahwa model praktikum berbasis Simulink dapat merepresentasikan alat praktikum sesungguhnya. Saat beban resistif nilai pf  = 1. Saat beban resistif-induktif nilai pf turun berbanding terbalik dengan nilai induktansinya. Saat diberikan kompensasi dengan memasangkan kapasitor dengan nilai yang tepat nilai pf dapat naik kembali mendekati 1

Purpose The aim of this paper is a steady-state analysis of the basic electrical characteristics of a wind farm with squirrel-cage induction generators (SCIG), integrated into a high power system. The SCIG are connected to the system by means of a step-up substation 21/115 kV, realized by cable lines. Design/methodology/approach The analyses have been done with the help of a computer model, developed in MATLAB/Simulink. Findings Results have been obtained, concerning the influence of the SCIG on the active and reactive power, on the power factor and the voltage deviation in the cases of only one generator operating, all generators operating and disabled generators. Practical implications The analysis has been carried out for an operating wind farm in the power system. The obtained results are applicable for optimizing and managing the modes of operation of the wind farm. Originality/value A mathematical model for studying the electrical parameters of an SCIG integrated into a high power system has been described. A computer model in MATLAB/Simulink has been synthesized. Numerical results have been obtained, concerning the dependence of the active power, the reactive power, the power factor and the voltage deviation on the shaft torque of the wind farms with SCIG.

Simulation Results

A simulation model of 230kV substation primary system and TSC+TCR typed dynamic reactive power compensation control system was constituted with RTDS, and the feasibility of control system with a case was validated. The control system was to monitor the variation of power system equivalent susceptance with sampling the power system voltage, established the relationships between power system susceptance and the firing angle of TCR, adjusted TSC switch and TCR firing angle to dynamically compensate the reactive power of power system. The simulation results demonstrate that the control system can guarantee power system voltage stability and real-time adjust power factor.

The Heat Balance

Accidents of icing on catenary have great impacts on normal operation of trains. An on-line anti-icing technology used static var generator (SVG) for catenary was proposed, which can prevent icing formation without interrupting trains normal operation. The heat balance equations for catenary were solved, whose results were compared with data provided by TB/T 3111 and testing show the equation was correct. The simulation model based on Matlab was bulit , whose results and analysis show the correctness of the method.
