Selected functions of the Area Voltage Regulation System (SORN) have been implemented in the Bydgoszcz Power Dispatch Centre (ODM) where the method of voltage situation assessment described in this paper has been utilised. The method of automated control over the ARNE and ARST regulation systems operation elaborated in the SORN system aims at supporting dispatchers during the ongoing regulation status assessment, danger conditions detection and counteracting the system malfunction results. This aim has been achieved by utilising the method of voltage situation assessment in the transmission grid which used normalized numerical indices describing the regulation nodes operation point. Next, the analysis of trends related to changes in these indices was used for detection with time advance of adverse changes in the voltage profile or reactive power reserves level. The described method employs the fuzzy inference system in order to generate prompts for Power Dispatch Centre (ODM) dispatchers. The limited SORN system functions fulfilled presently are to enhance the power system safety using the existing ARNE and ARST regulation systems infrastructure. Together with the latest modifications of the ARST system algorithms, the SORN system's basic duty is to prevent worsening or accelerating a voltage malfunction, which results from transformer regulation not being blocked on time.
