Question

This assignment is a modelling and analysis project which considers the impact of connecting a wind farm to the electrical network illustrated in Figure 1. The network model which is built using Simulink/MATLAB, will be given to you as part of this assignment (the model is incomplete and must be completed by the student as part of this assignment). Two of the scheduled workshops for module KD7070 will be allocated to explain the model and make the students familiar with the model. The Simulink diagram is shown in Figure 2. The upstream 132 kV network is represented by a Three-Phase Source block to represent the upstream network. The short circuit power and X/R ratio of the upstream network are 2000 MVA and 7, respectively. A traditional gas-fired generator is connected to the 132 kV bus through a 13.8 kV/132 kV transformer. This generator is a synchronous generator, and its nominal voltage and power are 13.8 kV and 150 MW, respectively.

Answer 1

The question involves engineering principles related to power generation, specifically the integration of a wind farm into an electrical network, modeled via Simulink/MATLAB.

Step-by-step explanation:

The correct answer is option Engineering. The question pertains to a modelling and analysis project involving a wind farm and its integration into an electrical network, using Simulink/MATLAB for simulation.

The information provided outlines the specifications of both the wind farm and the existing electrical network, including generator types, transformer voltages and power ratings, and the short circuit power and X/R ratio of the upstream network.

This analysis is critical for understanding the effects of introducing new power generation sources on existing infrastructure, particularly in terms of voltage transformation and power transmission efficiency.

It proposes an educational task to understand how transformers are used to step up the voltage from power plants like wind farms for efficient long-distance transmission, and then step it down for local distribution. This is key for the transmission of electrical power with minimal losses.

A wind farm is being connected to an electrical network in this modelling and analysis project. The network model is built using Simulink/MATLAB and is provided as part of the assignment. The Simulink diagram in Figure 2 shows the upstream 132 kV network represented by a Three-Phase Source block.

A traditional gas-fired generator is connected to the 132 kV bus through a transformer. The generator is a synchronous generator with a nominal voltage of 13.8 kV and power of 150 MW.
