It is known, that Flexible Alternating Current Transmission Systems (FACTS) are the core of the High Voltage Smart Grid technologies. Wide Area Measurement Systems (WAMS), using Phasor Measurement Units (PMU), open up new opportunities for power system monitoring and control. United Power System of Russia, having high generating capacities, is the most extensive power system in the world, stretching for thousands of kilometers through 7 time zones. For these reasons, close attention have always been paid to long-distance power transmission issues. This paper presents the methodology for data validation improvement for real-time power system monitoring and assessment of long-distance power transmission lines parameters, including controllable series and shut reactive power injection. The basis for data validation is two-stage a priori remote metering processing, including load- and weather-dependent transmission line parameters identification and update as well as local bad data elimination.
