| Summary: | Normally for oil and gas offshore platform, the electrical power supply is generated
from the generator either using gas turbine generator, gas engine generator and diesel
engine generator. The main power supply is backup by diesel engine generator in case
emergency or during black start of the platform. As the design of oil and gas platform
become complex, the size of generator keeps increasing. A new concept is being
explored to mitigate this problem. Oil and gas company is looking to provide power
generation from onshore and supplying the electrical power to a substation platform
offshore and then distributed it to various platform. Even though the idea is feasible, but
there is a challenge technically. One of the technical expect that need to be carefully
consider is the Ferranti effect over long transmission line, in this case the submarine
cable. Therefore, some study needs to be done to analyze the stability of the power
system when a system is connected to long submarine cable. When there is long
transmission line, the tendency of Ferranti effect to occur is likely. So, this study is
performed to study the magnitude of Ferranti effect on the propose system and how to
mitigate this power stability issue. A load flow study is perform using ETAP software to
determine the effect of Ferranti Effect on difference length of submarine cable. Shunt
reactor is used as the mitigation method to the Ferranti Effect. This study also
determined the size of shunt reactor required over the length of submarine cable. Short
circuit study was performed to determine the short circuit level at the receiving end for
different length of submarine cable. This short circuit level is crucial in determined the
rating of switchgear at the offshore. |
