【 摘 要 】

In a document titled "The National Critical Infrastructure Protection Programme" developed by the Government Centre for Security in the Republic of Poland, 11 systems falling within the critical infrastructure were characterised. These systems are essential for proper functioning of the country. Their carried-out tasks provide the continuity of the administrative structure functioning, as well as protect citizens from different kinds of danger (both external and internal ones). The safety of critical infrastructure facilities depends not only on the applied individual technological and procedural solutions in these systems but also on their power supply systems' proper designing and operation (also including electromagnetic interferences). Therefore, in this article, the authors analysed the power supply systems that can be used in the critical infrastructure facilities. However, only supplying electricity to the device is not equivalent to provision of its operation continuity and the appropriate level of values of the reliability and exploitation indices. Therefore, redundant power supply systems are used. The power supply system composed of two independent power sources was subjected to the safety level assessment. The obtained results will make it possible, among others, to rationalise the energy system structures.
