INTRODUCTION 1.1 Background Power systems have evolved from the original central generating station con-cept to a modern highly interconnected system with improved technologies a ecting each part of the system separately. The techniques for analysis of power systems have been a ected most drastically by the maturity of digi-tal computing.

1.3 PLC power supply A DC power supply is required by the PLC for low-level voltage used by the CPU, as well as for the I/O and communication modules. More often than not, a separate power supply module mostly supplies power. This is located beside the CPU unit or the external power supply, depending on the PLC vendor.
