Embodiment
The coordinated control system of a plurality of opertaing devices in a kind of electric system as described in Figure 1 comprises the opertaing device via measurement substation, central control computer, a plurality of control sub-station and a plurality of electric system of communication port connection.Wherein, for the time delay that ensures the reliability of communicating by letter between central control computer and opertaing device and communication at tolerance interval, between central control computer and a plurality of opertaing device by point-to-point optical fiber private line access independent of each other.In the present embodiment, the transfer rate of point-to-point optical fiber special line is 2M/s, also can adopt the transfer rate of 8Mb/s or 10Mb/s certainly.
Measuring the substation is used to gather the real-time power network data and mails to central control computer.
The multi-input multi-output controller module has been set up in central control computer inside, central control computer receives from the real time data information of measuring the substation, online carry out electric power system model and parameter identification after, adjust the multiple-input and multiple-output module parameter, again the electrical network multidate information is sent to the multiple-input and multiple-output control module, and obtaining corresponding multichannel steering order after calculating, the control sub-station in a distant place is mail in this instruction by high speed communications link.
A plurality of control sub-stations are controlled the opertaing device of a plurality of electric system, and the action of a plurality of opertaing devices of united and coordinating, promote the purpose of electrical network overall dynamics performance.In the present embodiment, opertaing device comprises any one or more combination in power system stabilizer, PSS, electric system high voltage direct current control system and the STATCOM.
For the reliability service that guarantees coordinated control system self and the safety of electrical network, this central control computer inside also establishes abnormal conditions Decision Control module, it is used for when abnormal conditions appear in opertaing device, and the orchestration control system withdraws from state of a control steadily, and locking output.
The initial parameter of input, output control module can calculate via simplifying the electric power system model and the theory of optimal control.Simplifying electric power system model carries out obtaining behind the rational depression of order to true electric power system model, the core information that has as far as possible kept original electric system when reducing system's dimension and mathematics manipulation difficulty greatly is as crucial mode of oscillation, crucial oscillation frequency etc.For the model of simplifying, can use the theory of optimal control, this theory can be according to the parameter of expectant control target design multi-input multi-output controller, to realize optimization and the coordination between the multichannel input and output control loop specially at multi-input multi-output control system.
