Reliance on liquefied petroleum constitutes an important economic cost on Ecuadorian society and the Ecuadorian State due to the high cost in imports. In order to achieve energy efficiency a replacement for GLP must be found. The aim of the present thesis is to conduct an electrical study with networks of medium voltage in their current state. The components of the network include the transformers, fuse disconnectors, drivers and clients, subsequently making the simulation with the connection of the electric ovens of induction. The study took place in the North Primary Feeder energy plant. It began with transmission of energy from the plant, until the last client connected. This was an essential part of the study, and especially with the future implementation of the electric induction ovens, program put forth by the National Government. The power of the electric induction ovens taken for the present study was 3 Kilowatts kW, considering a factor diversity of 0.8; therefore the power of each oven per user connected was 2.4 kW, the National Electrical Code from US was used as a model and can be seen in Figure 16. The factors of diversity for the different powers of ovens that will be admitted to our environment are included in the figure. The maximum demand of the Primary Feeder North in current conditions is 1996 kW. The demand for power is growing from 4 percent per year to 59.88 kW per year. In 10 years, the new demand will be of 2594.8 kW, but due to the losses by driving the new maximum demand is 2546 kW per year. Now simulating the implementation of electrical induction ovens the maximum demand on the North Primary Feeder will be 4330 kW. To determine whether the transformers will be overloaded, they are prepared through detailed formulas in the point: F. 2.3 Determination of overloaded processing centers totaling 277 centers of transformation, could verify there will be 63 transformers that will be overloaded. Likewise, it was possible to verify that the exit of the substation will be necessary to realize the change of the drivers, since the installed gauges are 1/0 AWG - A.C.S.R while with the information of the simulation for the new maximum demand the drivers will be a number 4/0 AWG - A.C.S.R, for the increase of this load. The entire length of drivers needed to be installed will be 2459, 23 m, starting from the pole number 128952 up to the pole 129110, which is detailed in the Figure 26. |
