Numerical Simulation of Compressible Reactive Flows

WebEquations (5) and (6 ) have the following remarkable feature: real power equations are decoupled from the voltage magnitudes, and reactive power equations are decoupled from the angles. The implication is that either one of equations (5) and (6) may be solved independent of the other one! WebThe equations at bus 1, 3, and 4 would remain the same with typical Q equations that take the summation of reactive flows going into the bus and sum them to zero. The equation at bus 2 however is replaced by a new equation that specifies that the flow on the branch arriving bus 1 from bus 4 is equal to the QV-characteristic function.
