多CPU内部通信测试技术研究及应用

Research and Application of Multi-CPU Internal Communication Testing Technology

摘要:

在电力系统保护与控制领域，多CPU协同工作已经是常见的应用方式，为了保证智能变电站继电保护与控制装置运行的可靠性，需要对多CPU间内部通信管理、数据异常处理等进行充分验证，以保证电力系统保护装置在各种工况下不会出现误动作；由于继电保护装置运行环境复杂，所有内部通信数据均是通过以太网总线直连，现阶段缺少对内部通信数据处理有效性的验证手段；采用在各CPU应用程序中设计一个专用检测模块，可以在不改变原有接线布局的情况下，对CPU之间的应用数据进行控制，从而验证了各种运行环境下多CPU板卡间内部通信的正确性，对智能变电站继电保护与控制装置的各种正常数据和异常数据处理能力进行充分的测试和验证，保证了保护与控制装置的运行可靠性。

Abstract:

In the field of power system protection and control, more CPU work has is a common way of application, in order to guarantee the reliability of the intelligent sunstation relay protection and control device to run, the need for more internal communication between the CPU data management, exception handling etc. To fully verify, to ensure the power system to the maloperation of the protection device under various conditions will not; Due to the complex operation environment of relay protection device, all the internal communication data processing. Uses in each CPU application design a special detecting module, can under the conditions of without changing the origial wiring layout,to control the application of data between the CPU and various operating condition is verified the correctness of the internal communication between multiple CPU boards, the intelligents sunstation relay protection and control device of all kinds of normal data and abnormal data processing ability adequately testing and verfication ensure the reliability of the protection and control device.
