In the process of distributing electricity from the generator to the consumer, it goes through many processes and passes through several parts. Starting from the electric power distribution system, one of which is the distribution system. Considering that the scope of this distribution network is directly related and is located in an inhabited area, in addition to meeting technical quality requirements, it must also meet the requirements for being safe for users and familiar with the environment. In this distribution system there is a very important equipment in distributing electric power, namely the distribution substation. Because of the important role of the distribution substation, it must be protected from disturbances that may occur. One of them is the load imbalance between phases. In practice and in reality, in various locations of electric power distribution, a completely balanced load condition is obtained, mainly because of the large number of single-phase load groups that are serviced by a low-voltage three-phase distribution system. This is because the characteristics and types of electrical power user equipment vary with different consumer conditions and activities. To obtain load balance, load balancing is carried out between phases for load distribution so that load adjustments occur at distribution substations.

The Government's goal to make Indonesia an Maritime Country must be supported by all elements of society, especially is from the education sector. As one of the maritime education institutions to improve competent human resources in its field, it needs training and supporting facilities and infrastructure. One way to increase competence is to supply cadets with capabilities in the field of operation and maintenance of ship machining. Synchronous generator is one of the important components in ship machining. Therefore, the ability to operate and maintain generators is absolutely necessary for cadets in the world of work. Standard selection of generator in the Shipbuilding Laboratory follows Government standards through the Ministry of Transportation Regulations. To choose the best electricity generator, a special method is needed. The solution to this problem is the use of the Analytical Network Process (ANP) to determine synchronous generators that meet the quality standards and specifications of stakeholders.By implementing ANP, the synchronous generator is obtained according to quality standards with the specifications desired by stakeholders. In applying ANP, weighting is based on criteria, namely: durability, maintenance, spare parts, specifications and price. Then obtained an electric generator with appropriate quality standards and specifications.Results of data processing using the ANP method obtained electical generator alternative selection with each weight is adalah CUMMINS GFS-C30KW 41,6 %, HARTECH HT35Y 33,9 %, and CATERPILLAR C2.2 24,5 %.
