摘　　要：随着电力电子行业的快速发展,其已经广泛用于光伏发电、风力发电等新能源场站,这些设备的并入电网,对电网产生的不稳定性问题,需要进行仿真分析,为了搭建模拟实际设备控制性能,需要在不改变电力电子设备控制系统硬件和软件的基础前提下,将电力电子设备的控制系统真正的控制算法产生的控制信号传给仿真设备RTLAB,以便能够了解设备的真实性能,但是级联式电力电子设备控制系统功率单元光口较多,且为普通塑料光口,直接将这些普通光纤信号直接与RTLAB仿真设备连接显然不现实,所以实际的电力电子设备控系统的控制信号无法与RTLAB进行直接传输,除非编写特定仿真程序,下载到有高速光口的电路板上面,然后再与RTLAB设备进行连接,这样显然与实际电力电子设备的控制系统有区别,降低了仿真的可信性。为了解决这一问题,在实际级联式电力电子设备的控制系统与RTLAB之间增加一控制信号处理系统,将两边传输的信号进行解码,然后重新编码成两边设备通信可识别的信号,在电力电子控制系统的硬件与软件都没有改动情况下,完成系统仿真。With the rapid development of the power electronics industry,it has been widely used in photovoltaic power gwneration,wind power generation and other new energy stations.The integration of these devices into the power grid requires simulati on an a lysis of the in stability of the power grid.In order to build a simulati on of the actual equipme nt con trot performance,it is necessary to transmit the control signal gen erated by the real control algorithm of the power electronic equipment control system to the simulation equipment RTLAB without changing the hardware and software of the power electronic equipment control system,so that the real performance of the equipment can be understood.However,the cascaded power electronic equipment control system has many optical ports of power unit,which are ordinary plastic optical ports.It is obviously unrealistic to directly connect these ordinary optical fiber signals with RTLAB simulation equipment.Therefore,the control signals of the actual power electronic equipment control system cannot be directly transmitted with RTLAB.Unless you write a specific simulation program,download it to the circuit board with high-speed optical port,and the n conn ect it with RTLAB equipme nt,which is obviously d iff ere nt from the con trol system of the actual power electronic equipment,and reduces the credibility of the simulation.In order to solve this problem,the invention adds a control signal processing system between the control system of the actual cascade power electronic equipment and the RTLAB,decodes the signals transmitted on both sides,and then recodes them into signals that can be recognized by the equipment communication on both sides.The system simulation is completed without any changes to the hardware and software of the power electronic control system.
