Abstract
There are emergency automatics systems (EA) widely used in Unified Power System (UPS) of Russian Federation. Main focus of article is centered on design principles of preventive automatics for stability control schemes (PASCS) as this automatics is the most complex type of EA. Features of PASCS are determined by modern state-of-the-art of digital technique and information technology, that decide the innovative developmental character of PASCS. Information about development and implementation of centralized emergency automation systems (CEAS) in power systems of Russian Federation is also given here.
Highlights
Emergency automatics system is widely applied in Unified Power System (UPS) of Russian Federation
State-of-the-art level of computing technology allows to simplify essentially the problems of development of centralized emergency automation systems (CEAS) technological software due to namely limited abilities of computing technology, that required in due time to develop unique engineering reduction methods and calculation models of power system
Application of CEAS optimizes the scope of emergency control and increases transmission capability of power grid keeping required reliability level
Summary
Emergency automatics system is widely applied in Unified Power System (UPS) of Russian Federation This EA system is intended to on-time detection of emergency disturbances and to prevent the evolution and to eliminate danger emergency modes in power system [1,2,3,4,5,6,7]. Secure and effective operation of power system EA is assured by means of application of centralized and decentralized emergency control, implementation of hardware and functional redundancy principles, independent operation of each above EA subsystem Such approach of EA designation allows to ensure: effective emergency control including appearance of non-standard emergency disturbances, considerable restriction of the emergency modes distribution in power system, minimum time to eliminate these emergency mode and normal operation recovery in power system. CEAS of third generation was developed and put into operation at CPS of East Region in 2014 [11]
