FREQUENCY AND TIE-LINE POWER-CONTROL WITH PARALLEL OPERATION OF THE POWER-SYSTEMS OF RUSSIA AND EASTERN AND WESTERN-EUROPE

This paper deals with the efficiency of various methods for frequency and tie-line power control for the forthcoming connection for parallel operation of the interconnected power systems of Russia and Eastern a nd Western Europe (UCPTE). For research investigation, a digital non-l inear dynamic model of the interconnected power systems as a controlle d plant for the load-frequency control system has been constructed. Mo del analysis of frequency and tie-line power transients in this ultra high-power interconnection for disturbances of various kinds has shown that parallel operation through the East-West tie-line now under cons ideration is quite possible if there are efficient load-frequency cont rol systems in all the power systems interconnected for parallel opera tion.
