| Summary: | The advancement of technology had encouraged mankind to design and create useful equipments and
devices. These equipments enable users to fully utilize them in various applications. Pulp mill is one
of the heavy industries that consumes large amount of electricity in its production. Due to this, any
malfunction of the equipment might cause mass losses to the company. In particular, the breakdown
of the generator would cause other generators to be overloaded. Thus, load shedding scheme is the
best way in handling such condition. Selected load will be shed under this scheme in order to protect
the generators from being damaged. In the meantime, the subsequence loads will be shed until the
generators are sufficient to provide the power to other loads. Once the fault had been fixed, the load
shedding scheme can be deactivated. In order to determine the sequences of load shedding scheme,
analytic hierarchy process (AHP) is introduced. Analytic Hierarchy Process is one of the multi-criteria
decision making methods. It had been used in solving a lot of decision making problems since ages
ago. AHP is widely used in comparing the options in order to achieve the goal. For the application of
AHP in load shedding, the operating load and the area power are chosen to be the criteria. The options
of each criterion will be the load of the electrical system in the pulp mill. On the other hand, fuzzy
AHP is the advanced version of AHP which can solve the uncertainty of the pair-wise comparison and
gives more accurate results in fuzzy situation. This paper presents the alternative methods to choose
the load priority in load shedding scheme for a large pulp mill. The results of the AHP and fuzzy AHP
analysis to the pulp mill are very promising. |
