PLC-based surveillance system for electrical installations in buildings

The paper presents technological solutions for the operation management of electrical installations that are designed to include micro power sources. For that purpose, the technological potential offered by programmable logic controllers (PLC’s) has been applied to the building management system. The development of electricity generation technologies makes it possible for a private person and micro companies to install local power sources that are directly connected to their own power supply wiring. The paper presents characteristics and technological potential of surveillance and control systems designed for low power sources connected to low voltage network systems and electric wiring in buildings. Possibilities concerning the integration of the source operation control with the building automation system as well as the power consumption control have been presented.
