Development of Power Management System for Electric Power Generation in Tanker Ship Based on Simulation

Abstract

Abstractpower management system (PMS) for electric power generation in ship especially on tanker ship keeps growing. The system has a function to control and monitor all generators in ship as the main electricity supplier for all electric equipments or installed load. The number of total load that supplied by generator depends on the frequency of the load itself which would be read in PMS as well. It help the operator to make a decision about how many generator should be operate whether in parralel or in a stand alone operation to fulfill the required power. Those loads should be grouped into essential and non-essential load. This groups affecting the performance of the generators, where it will covers the maximum load at 306.67 kw under the condition of all electric equipments are well operated while the cargo handling of tanker ship is on process. However, in the state of emergency while the non essential electrical equipments are being cut off trough PMS, the generator will only covers the the maximum load at 253.88 kw to fulfilling the same required power. In the extreme case (total efficiency of parralel operation at 70%), the generators would cover the total load at 306.6 kw by sparing the generate power of 52.72 kw.

Design of Protection Coordination for Overcurrent on Electrical System in Tanker Ship Plan Using Electro Mechanical Trip Device

“…But overcurrent was not only affected by short circuit. It could be affected by overload in electrical system [11].…”

“…When a short circuit occurs with voltage applied the decrease in resistance results in a short circuit current that can be thousands of times higher than normal operating current. The heat generated by this current will cause extensive damage to connected equipment and conductors unless current is interrupted immediately [11][12][13][14].…”
