<strong>ملخص الدراسة:</strong>

The availability and continuity of electrical power sources in sensitive building like hospitals is very important issue. Due to the unstable power grid conditions in Gaza Strip, inefficient amount from the main electrical power supplied by public grid, and risk of electrical power fault occurring daily, sensitive building are provided with extra alternative supplies (Diesel Engine Generators). This thesis will propose a design (solution) for main traditional electrical distribution boards and automatic and manual transfer switch (ATS & MTS) to ensure availability and flexibility of electrical power supply for all loads in hospitals under all circumstances. This thesis will also propose a control mechanism which contributes in reducing fuel consumption used by power generators by measuring power consumption and transferring loads to suitable size generator to avoid high loading (may damage the generator) or low loading (high fuel consumption related with power produced) on generators. In this thesis we use KAMAL EDWAN hospital's electrical power system as a case study. The results are obtained by applying the proposed control approach using programmable logic controller, PLC unit, to ensure generator loading within 40% to 85% of its rated capacity under special circumstances that leads to the best efficiency fuel consumption.
