A Research On Distributed Parallel Calculation Management Mode Considering Spatial And Temporal Dimensions

The decomposition and coordination calculation among multiple control centers can solve the contradiction that power systems have been interconnected while they are managed and controlled hierarchically. But distributed calculation is a complex process which involves problems about multi-regions, multi-users and multi-applications, therefore the distributed parallel calculation management mode is needed for realization. So the decomposition and coordination calculation needs not only to deal with the independent calculation process among different subsystems, but also to form a distributed calculation management mode considering multi-users paticipating in starting multi-applications. So it is necessary to stady specific parallel calculation mode to solve the problems above.To solve the problems that applies the decomposition and coordination calculation to the reality, provide the access platform for mutiple distributed applications, this paper designs the distributed parallel calculation management mode from realistic point of view. It uses the decomposition-coordination mechanism to deal with the calculation relationship among different users, different subsystems and different applications; it uses the master-slave mechanism to improve the accuracy of calculation; it uses the parallel calculation mechanism to mark the objects with time, space and application dimensional coordinates to realize the isolation and stratification of data. This paper uses C++programming to vertify the correctness of the management mode:distinguished and realized the management and calculation process with objected design; defined the IDL interface to solve the communication between the decomposition layer and subsystems.The distributed parallel calculation management mode can realize the classification of the objects and the stratification of data. It can realize different users among different subsystems start different applications at the same time. The distributed parallel calculation management mode provides the access platform for multiple distributed applications, and makes a useful exploration to try to design and realize the new generation of EMS with 3 dimensional coordination.
