Abstract [en]

This thesis analyzes the generator loss of excitation fault and describes an investigation on existing loss of excitation protection schemes. In addition, a simulation model is established in PSCAD to simulate the loss of excitation fault and external faults.

According to the simulation results, this thesis compares the speed of different protection schemes on loss of excitation fault detection and finds the drawbacks of some protection schemes on fault detection during special operation condition.

What’s more, this thesis also compares the stabilities of different loss of excitation protection schemes during generator external faults.

Finally, this thesis summarizes the advantages and disadvantages of different schemes and serves as a reference for selecting the loss of excitation protection scheme.
