摘　　要：风电变流器系统非常复杂,要观测的物理量非常多,对监控软件的实时性和稳定性要求较高。该文从实际的工程应用出发,设计了一款适用于风电变流器实时监控的虚拟示波器软件。软件采用VS2010编程,充分利用了MFC的多线程技术和消息机制,为用户提供了友好的人机界面,实现了对风电变流器参数的高速实时采样、实时显示、实时保存等功能,保证了对风电变流器运行状态的实时监控。文中给出了软件的整体构架,详细介绍了软件各个部分的设计与实现,并对软件的运行效果进行了测试,给出了软件的运行效果图。通过测试,虚拟示波器软件波形显示正常,运行稳定,各部分功能满足设计的要求。A higher real-time and stability of monitoring software is required as the complex wind power converter system has so many physical quantities to observe. A virtual oscilloscope software used for converter real-time monitoring is introduced in this paper with the view of engineering applications. Based on VS2010 integral programming environment and MFC database, the software makes full use of multi-thread technique and message mechanism, provides users with a friendly interface, realizes high- speed and real-time sampling of converter parameters, real-time display and real-time save functions to ensure that the wind power converter runs properly. This paper presents the overall architecture of the software, detailed design and implementation of various parts of the software, and tested running renderings. Through the test, the virtual oscilloscope software operates stably with each function meeting the de- sign requirements.
