Step (2): control system mirror image obtains the emulation teaching notes in analogue system memory module, and is stored in control system memory module; Grid simulation module starts emulation according to emulation teaching notes;
Step (3): the real-time simulation electric network data obtained after grid simulation modular simulation is sent to control system by simulation service system regulation and controlling of information service module; In this step, after grid simulation module starts emulation, the generation load of simulated grid and power system operating mode start change, and up-to-date real-time simulation electric network data and electric network swim (comprising the data such as meritorious, idle, voltage) are sent to control system regulation and controlling of information service module by simulation service system regulation and controlling of information service module.

Step (2) comprises further:
Step (21): grid simulation module is according to emulation teaching notes simulated grid power flow changing, and in simulation process, Information Statistics module adds up electrical network evaluate parameter, and emulation duration is one-period; In the present embodiment, one-period is 24 hours, owing to preserving in emulation teaching notes, generated power is exerted oneself, set end voltage curve, the data of the actual electric network generatings such as load is gained merit, idle curve, load curve, grid simulation module can according to above-mentioned data automatic power generation adjustment, load meritorious, idle and set end voltage, electric network swim change during the change of emulation daily load, and in simulation process programming count voltage cross the border, the parameter such as network loss situation and switch changed position number of times.In this step, AVC system wouldn't participate in controlling, and emulates one-period alone, be convenient to contrast with the situation of an emulation cycle under later stage AVC Systematical control, to compare the control effects of AVC system better by grid simulation module.
Step (22): second period starts, start the AVC system of control system, control system mirror image obtains the emulation teaching notes in analogue system memory module, and be stored in control system memory module, electric network model on Guarantee control system electric network model and simulation service system is completely the same, thus ensures that DTS system is consistent with the electric network model that AVC system uses; Grid simulation module restarts emulation according to emulation teaching notes, identical with the beginning data ensured with the period 1 emulate, and elimination biological factors, being convenient to the later stage compares.
In the process of above-mentioned control imitation, after the grid simulation module of DTS system and Information Statistics module terminate at each AVC control cycle, steering order simulated, all record complete simulation snapshot section, the data that simulation snapshot comprises have: the Branch Power Flow of all circuits of the whole network, main transformer; The injection trend of all units of the whole network, load; Voltage, phase angle, the frequency of all buses of the whole network; The state of all switch tools of the whole network; The all main transformers of the whole network state separately.On the basis of these simulation snapshot data section, can analyze whole emulation cycle, analyze and comprise following content:
