A PROPOSED LOAD SHEDDING SCHEME FOR EG LNG PLANT

Load shedding schemes are important and powerful tools nowadays for power
systems. Load shedding is used as last resource to save islanded systems -under
generation deficiency - from collapse. This report presents a prepossessed
methodology for a design of automatic under-frequency load shedding scheme. The
network of Equatorial Guinea Liquefied Natural Gas Plant has been chosen for
implementation. The project involves one main objective which is to design and
implement, through simulation, an automatic load shedding scheme suitable for the
network. The plant load is divided into different categories. An under-frequency load
shedding scheme base on rate of change of frequency, disturbance estimation and
load categorization priority is designed to unable the plant to operate critical
(mandatory) loads in the event of insufficient system generation. Project planning and
implementation flow are also reported here.
