Abstract
In this research we have defined the whole effects and parameters that effect on evaluation of Iraqi system frequency and then they take standard values like network parameters,distant relay ones, evaluation of stored energy and speed drop characteristics…etc. In case of frequency drop than distant relays worked at it then the mechanical ability to compensate deficiency in power for which this drop happened works to increase frequency in the following cases: 1- Any load shedding in case of distant relay respond for this deficiency. 2- No load shedding for any part of system load. Then the frequency of system increased its value to compensate the worked generator units with instantaneous stored energy stored which would work in this case as additive from stored energy then this will change the values of parameters and effects which have been fixed before frequency value reduction and this affect the value of frequency to reach value of frequency before power disturbance. This conclude that there would be a computer model for electrical Iraqi system that worked with standard and instantaneous values of generation units operations and this model here is for studying in this research (that nobody in past get in this field ).This model works according to mathematical equations for parameters and effects of this network .That mean that no treatment exist before in this field and this depend on the base of parameters values stability of network and variations effect of other generator units parameters since the sudden stoppage of any sudden generator unit(s). At end of this research, a mechanical work of this model as a computer model has been represented as a compact computer system (derived by us) with cooperation of iraqi national electrical center (control engineers and operators).
