EN Load flow calculation and analysis in DAKAR complex is carried out using the method of compensational electromotance (optimization of Jacobi matrix conditioning, per-node Newton linearization). Electric condition is well balanced during every iteration, which is the characteristic feature of this method. Convergence monitoring is performed and if the condition does not exist, the closest found condition is recorded. The method gives a possibily to calculate normal, marginal and postemergency conditions both with or without frequency alteration, also when the power system is composed of several subsystems each with different frequency value. DAKAR features of the possibility of recording the highest estimated limits of generators reactive power. In the process of load flow calculation the highest limit is calculated taking into account the generator parameters specified in the current node, the number of generators, the voltage of a given node and the actual load of generators with active power.
