Electrical Networks of the Azores Archipelago

Abstract

In this chapter, the electrical networks of the Azores Islands are explored. In the Azores Archipelago, smaller islands like Corvo, Flores and São Jorge have radial distribution networks. Larger islands such as Graciosa, Faial and Santa Maria have ring distribution systems located along the coastal area. In addition, the largest islands like Terceira and São Miguel have high voltage transmission systems connecting large generators to large load centers. Only Terceira and São Miguel have advanced control centers that handle generation control and distribution management.

Appendices

Appendix A

Appendix A includes the steady-state characteristics of the electric power system of Flores in PSS/E v. 23. The data is available in the CD attached to the book.

Appendix B

Electromechanical and electromagnetic parameters of the power plants on Flores are presented in Tables B.1–B.6. These parameters are estimated based on the data set provided by Professor Pecas Lopes from INESC Porto [4] and based on the models used in [3]. The original data set is available in the CD attached to the book. The bases are Sbase = 1 MVA, Vbase = 0.4 kV, and fbase = 50 Hz.

Appendix D

Electromechanical parameters of the power plants in São Miguel are presented in Tables D.1–D.15. These parameters are estimated based on the data set provided by Professor Pecas Lopes from INESC Porto and Professor Pedro Carvalho from IST Lisbon and based on the models used in [3]. The bases are Sbase = 100 MVA and fbase = 50 Hz.
