Abstract: A power system monitoring and control system having a thread-dependent calculation monitoring function is provided. The power system monitoring and control system includes: a display unit displaying screen information; a calculation handling unit executing thread-dependent calculation based on a calculation expression defined in a calculation file, and performing calculation handling for generating calculation result information and thread-dependent calculation execution monitoring information to provide generated information as screen information on the display unit; and a data storage unit storing file information for power system monitoring and control, information on the calculation file, the calculation result information, and the thread-dependent calculation execution monitoring information.
