Detailed description of the invention
Also with reference to accompanying drawing, the present invention is described in further detail below in conjunction with embodiment。
Embodiment 1:
One embodiment of the present of invention, uses Fastest software and SSFNet software to carry out the comprehensive simulating of electrical network and communication network, and wherein Fastest software is used for electric analog, and SSFNet software is used for communication simulation。Its comprehensive simulating flow process is as shown in Figure 1。
First, definition electric analog and SDH communication scenes respectively, wherein the definition of electric analog scene mainly includes topology design, trend configuration, power failure information arranges and control prediction scheme is arranged。The definition of SDH communication simulation scene mainly includes SDH topology design, communication port configuration, communication failure arranges and fault recovery prediction scheme configures。
Secondly, it is respectively started communication simulation。Electric analog software Fastest selects corresponding control strategy according to power failure information, according to control strategy, selects to control passage accordingly, then control channel information is sent to communication simulation software SSFNet。After communication simulation software SSFNet receives channel information, update simulating scenes configuration file, the above-mentioned communications status controlling passage is started the communication simulation of SDH。When communication simulation starts, electric analog software Fastest only receives the result of communication simulation, until communication simulation terminates and receives all of communication simulation result。
SSFNet is when carrying out the communication simulation of SDH, simulation result is sent to electric analog software Fastest by SOCKETUDP packet, detailed process is as shown in Figures 2 and 3: time initial, first communication simulation software SSFNet is started, and it is at waiting state, then start power system simulation software Fastest。When communication simulation software SSFNet receives from power system simulation software Fastest " start " signal transmitted (Fig. 3) time proceed by communication simulation, in communication simulation process, during generation communication event, (communications status changes, such as communication disruption, communication recovery etc.), communication simulation software SSFNet will hang up, and the status information of each communication port of previous stage is sent to power system simulation software Fastest, data form is as shown in Figure 4。Power system simulation software Fastest sends after receiving this information and confirms that packet " resume " is (in Fig. 3With), communication simulation software receipt is after packet " resume ", and SSFNet continues emulation。Repeat above step, until communication simulation terminates, and by end signal " end " (in Fig. 3) it is sent to Fastest software。
Finally, after power system simulation software Fastest receives whole communication simulation status information, calculate the maximum communication time delay of each communication port。If there being communication port generation communication disruption, then the communication delay T=T1+T2(T1 of this passage is the channel interrupt moment duration to the communication recovery moment, and T2 is the transmission delay of this communication port after communication recovery)。Set communication to break down with electric power, then the control time delay of power system is just for T simultaneously。Update the bug list file middle filling machine of electric analog or the execution time of cutting load, then proceed by electric analog, and finally show simulation result。
