【摘要】：随着机组容量的不断增大,考虑机组动态特性的AGC控制过程一直没有适合在实验室中进行研究的实验平台；新能源尤其是风电大规模接入电网带来了复杂的电力系统稳定性问题,然而目前也没有一个合适的动力系统仿真工具能够对大规模风电并网的功率平抑过程展开研究。因此,本文基于RTDS平台,提出了源网联合仿真控制系统的设计方法,并对系统中的接口技术进行了详细研究。 源网联合仿真控制系统主要由三大模块：电源仿真模块、电网仿真模块、调度系统仿真模块组成,本文详细介绍了各模块的功能、各模块间的关键接口技术以及实现方法。 电源接口模块通过RTDS的光纤通讯接口卡GTFPGA实现与RTDS电网模块的数据交互。火电、水电仿真机通过在RTDS中搭建的接口控制模块接入电网仿真模块,接口控制模块接收来自详细仿真机的机械功率参考值调节发电机的实际出力；非详细仿真发电机组通过在RTDS上搭建的功频调节控制模块接收调度指令调节发电机的实际出力。风电场详细仿真机通过风电场自定义接口模块接入RTDS电网仿真模块,风电场自定义接口模块为基于RTDS/CBuilder平台开发的一次系统模型,可以通过接收风电场详细仿真机的功率指令调节风电场的实际出力。RTDS电网仿真模块通过以太网通讯接口GTNET-DNP以及串行器模块,配置点映射文件,实现与调度系统仿真模块的数据交互。电源仿真模块以RTDS为中介实现与调度系统仿真模块间的数据交互。 本文提出了源网联合仿真控制系统的实现方法,解决实现了系统三大模块间的接口技术,应用蒙西电网的实际数据,证明了电源、电网、调度系统间接口方法的正确性及可行性。模拟实际电网中风电场的运行状况,验证了源网联合仿真控制系统的整体功能。
[Abstract]:With the increasing of the unit capacity, the AGC control process considering the dynamic characteristics of the unit has no experimental platform suitable for research in the laboratory. New energy especially large-scale wind power grid brings complex power system stability problems. However there is no suitable power system simulation tool to study the power stabilization process of large-scale wind power grid. Therefore, based on the RTDS platform, the design method of the joint simulation control system based on the source network is proposed, and the interface technology of the system is studied in detail. The system consists of three modules: power simulation module, power network simulation module and dispatching system simulation module. This paper introduces the function of each module, the key interface technology between each module and the implementation method. The power supply interface module realizes the data interaction with the RTDS power network module through the RTDS fiber communication interface card GTFPGA. The interface control module of thermal power and hydropower simulator is connected to the power network simulation module through the interface control module built in RTDS. The interface control module receives the mechanical power reference value from the detailed simulator to adjust the actual output of the generator. The power and frequency regulation control module built on RTDS is used to control the actual output of the generator by receiving the dispatching instruction. Wind farm detailed simulation machine is connected to RTDS power network simulation module through wind farm custom interface module. Wind farm custom interface module is a system model based on RTDS/CBuilder platform. The actual output of wind farm can be adjusted by receiving the power instruction of the detailed simulator of wind farm. RTDS power network simulation module can configure the mapping file by Ethernet communication interface GTNET-DNP and serial device module. Realize the data interaction with the simulation module of the scheduling system. The power simulation module uses RTDS as the intermediary to realize the data interaction between the power supply simulation module and the scheduling system simulation module. In this paper, the realization method of the joint simulation control system of the source network is put forward, and the interface technology between the three modules of the system is solved. The actual data of the Mengxi power grid is used to prove the power supply and the power network. The correctness and feasibility of the interface method between dispatching systems. The operation of wind farm in real power network is simulated, and the whole function of the combined simulation control system of source network is verified.
