5.2 specific implementation procedure
Through the modification of the real-time data of the intelligent power grid dispatching technical system, the intelligent control of the AGC is realized through the data interaction of the network side RTDS software data channel and the network side RTDS simulation system, the AGC transmits an instruction to the RTDS through the data transmission channel, the effect of intelligent control of the intelligent AGC of the thermal power generating unit is realized, and the artificial influence is reduced.
The modeling obtained in the experiment is based on dynamic characteristics of different power supplies and known parameters related to the generator provided in a BPA data file, and a consistent generator model can be built on an RTDS platform based on different power supply models which can be simulated by RTDS, such as thermal power, by combining parameters and control logic related to an excitation system, a stabilizer and a speed regulator system. The classification and explanation are made below on the grid-connected mode of the thermal power generating unit.
The thermal power generating unit model built on the RTDS platform can be further refined into two types, namely a non-detailed simulation generator module which directly responds to the control instruction of the dispatching side and a detailed simulation generator module which receives and forwards the control instruction from the dispatching side to the intelligent power grid dispatching technical system of the source side.
For convenience in explaining the real-time simulation measurement sending out of the power grid model and the sending, receiving and forwarding of the control command, the description is made here in connection with the dispatching EMS system. As shown in fig. 1, a detailed model of a thermal power unit is established on a source side smart grid scheduling technology system server, and a data channel is connected with an RTDS network side system through automatic input of a current design interface, so that real-time power climbing change of a thermal power simulator is accurately reflected in the RTDS. A non-detailed thermal power generating unit simulation model is established on the RTDS, the non-detailed thermal power generating unit simulation model is connected with the RTDS power grid model, the power grid model is connected with a smart power grid dispatching technology system, and at the moment, the uploading of real-time data is realized through an implementation channel, so that whether the development of an interface is effective or not can be verified. The automatic operation of the joint simulation comprising the thermal power unit, the RTDS power grid and the intelligent power grid dispatching technology system is realized, and the closed-loop control is formed by combining an EMS system, so that the application in a source network load simulation control system is satisfied.
And a non-detailed simulation generator power frequency regulation control module is built on the RTDS, and the simulation object comprises a coordination control system module, a speed regulation system module, a boiler module and a steam turbine module, wherein the relation among the parts is shown in figure 2. In the figure, omega is the rotating speed of a generator rotor, omega 0 is the rated rotating speed of the generator rotor, PM is the actual active output of the generator, TD is the output command of a main controller of a steam turbine, BD is the output command of the main controller of a boiler, CV is the opening command of a valve of the steam turbine, pT is the main steam pressure of the boiler, SF is the steam flow, and TM is the mechanical torque output by the steam turbine.
Setting up an interface control module of an RTDS power grid and a non-detailed simulation generator in the RTDS, manually controlling whether the non-detailed simulation generator receives the dispatching of an AGC system, if so, inputting an AGC command sent by an EMS to the RTDS power grid simulation module into the non-detailed simulation generator power frequency adjustment control module, and accessing the mechanical torque (per unit value) output by the AGC command into a corresponding non-detailed simulation generator body module. An example diagram of a non-detailed simulated generator interface module is shown in fig. 3.
The construction of the detailed simulation generator interface module, namely, a thermal power detailed simulation generator is transmitted to a generator outlet switch opening and closing instruction (0/1), a mechanical power reference value (named value) and a synchronous signal (0/1) of the RTDS power grid simulation module to serve as input quantities, and an interface control module of the RTDS power grid and the thermal power detailed simulation generator is constructed in the RTDS. The synchronous signal is represented by digital quantity 0/1, 0 represents that the RTDS power grid and the thermal power detailed simulator respectively and independently operate, and 1 represents that the RTDS power grid and the thermal power detailed simulator synchronously operate. When the synchronous signal is 1, the outlet switch state of the thermal power machine is controlled by a thermal power detailed simulator; and converting the mechanical power reference value into mechanical torque (per unit value) and accessing the mechanical torque to a generator body module of a corresponding unit of the thermal power detailed simulation machine. An example diagram of a detailed simulated generator interface module is shown in fig. 4.
When the signal is 0, the generator does not accept the dispatching of the AGC system, the active output of the generator is regulated by using the set value of the slider active, and the generator outlet switch command uses an initial value; when the signal is 1, the AGC command received by the generator from the dispatching system is converted into a per unit value, the per unit value is connected to a power frequency adjusting control module (shown in figure 3), the calculated result is connected to the generator body module in figure 4, and the generator outlet switch is controlled by a remote control command from the dispatching system.
In fig. 4, SYNDH1R is a synchronization signal sent from a power supply side thermal power detailed simulator, and the initial value of the synchronization signal is 0. When the synchronous signal is 0, the reactive power and the active output of the generator are regulated by the generator through the calculation result of the excitation system and the calculation result of the speed regulating system which are built in the RTDS, and an outlet breaker of the generator is controlled by the value of the switch. When the synchronous signal is 1, the generator uses the mechanical power reference value sent by the power supply side thermal power detailed simulation machine and converts the mechanical power reference value into a per unit value, the per unit value is connected with the generator body module to adjust the active output of the generator, and the outlet breaker of the generator is controlled by the value of the generator outlet switch opening and closing command sent by the power supply side thermal power detailed simulation machine.
