Electrical Modernization Central University Campus
External and electrical double power supply to the Central University Campus - Restructuring & redesign of the internal electrical grid.
The Fusion Research Group presents this actual project regarding the electrical supply systems oriented to establish our Magnetic Confinement Experimental Facilities into our Central University Campus.
This (R+D) Project involves multidisciplinary physics and engineering areas mainly those used to performing electrical studies in low, medium and high voltage, with main objective to establish conditions in the Electric Power System (EPS).
We define our parameters in voltage, current, frequency, to implement the correct strategies of electrical supplies (interconnections, structural composition of the feeding grid internally-externally, protection schemes, analysis of the burden demand, etc.).
The present project establish an electric engineering proposal to our University which includes studies over the ground electrical system grid, and the quality of the electrical power, as the electrical protections schemes, these studies were conducted by the Federal Electricity Commission (CFE, Spanish acronyms) and the Fusion Research Group.
The quality analysis of the energy consisted of measuring (analyzer AEMC Model 3945-b Power Pad) into the five constituent internal circuits of our Central University Campus (CUC), the next considerations: phase imbalances (current and voltage), harmonic distortion total and individual (voltages and currents of 1-50), transient capture, presentation of the power factor, registration of electrical interruptions and reclosing, measuring and recording quality power systems, crest factors (voltage and current), accurate RMS measurements of voltage and current, presentation of phasor diagrams.
​
The present project is a general and comprehensive review with a description about of the respective electrical analysis for all internal-external grid circuits with medium voltage (13.8 kV, nominal voltage) to avoid distortion, harmonics and transients on the power supply for the electrical feed to our experimental facility, these results concludes with an interesting proposal to redesign both electrical grids (internal) into CUC-UANL and the external one involving the Federal Electricity Commission ensuring the electrical grid stability during the possible operation of the Tokamak “T” in the UANL Central University Campus.
​
Electrical simulations (Aspen and Simulink) were carried out to reinforce our electrical redesign proposal to the protection schemes on medium voltage in the electrical external/internal grids and in the subtransmission lines into our University. The main objective is to supply and protect our magnetic confinement experimental facility, and ensuring electrical stability. Our proposal design of the Tokamak “T” has a coils arrangement capable for generate 1.3 T in the toroidal field, with a coil current range (10,000 – 30,000 A), short circuit times from 300, 500, 700 ms.
