With each passing day of enterprise business, work flow needs to be improved frequently, which proposes high requirements to the process definition tool. Through briefly introducing the concept of workflow and workflow management system, the foundational and importance of process definition has been pointed out in the workflow management system. Finally, giving the Design and Implementation of Process...
The instantaneous reactive power theory is widely used in the detection of harmonic and reactive current in three-phase circuit, and can also be used in single-phase circuit detection. This paper deducts the detection method in single-phase circuit by constructing two-phase system based on the instantaneous reactive power theory. An improved algorithm to obtain the key circuit components is presented...
According to Hurwitz's criterion, this paper deduces the steady state borderline of steam turbine with AVR on the map of reactive capability curves, using the mathematical model of one machine infinite bus system. It extends steam turbine's safe range under exciting operation compared to generator without AVR, and presents a proposal for the reactive power service market.
