ICOEUR (Intelligent Coordination of Emergency Operation and control of European and Russian Power Grid) is a project within which it is planned to develop the European and Russia, Belarus, Ukraine and the Baltic States energy optimal combination approach. Participate in the project 22 partners from 11 countries, including the Institute of Physical Energetic and Riga Technical University of Latvian. The project is implemented by the European Commission and the Ministry of Education (co-financing). One of the project topics is 330kV and 750kV electric ring-S.Pēterburga Moscow-Baltic-Belarus-Smolensk-Moscow modelling and features analysis. Research are made by authors with long-standing operational and technology management experience in static and dynamic stability estimates for the 330kV and 750kV electric ring as well as the development of technology management solutions, introduced the energy specialists, eliminating many situations of emergency. Longer period of time were carried out wiring and electrical parameters of the experimental tests in order to approximate the parameters used in the estimates of their real value. In paper described and analyzed a large power system operational and technological management of underlying problems, which are based on experience and requirements for electricity and electrical parameters. Energy research with dangerous emergency pre-assessment requires a well-ordered and an adequate mathematical model of the system, which would provide both stationary and dynamic electric mode estimates. A major requirement of dynamic electric mode estimates were special programs to check against emergency automation of complex causes efficiency in emergency situations, removing or restricting them to determine the effects the amount of power-generating capacity and changes in consumer load shutdown. Specific program was used iteration method. With a special program step by step was changed emergency automation of complex effects in addition to the quantity or set to automatic emergency centre, providing a stable after emergency treatment.
