一种实时高精度故障录波系统同步控制方法

针对目前国内故障录波器存在的录波文件数据不连续、功能单一、分析困难的问题，研究基于多处理器同步控制的故障录波数据监测系统，测试各功能在各处理器模块中的执行时间以及各模块接口访问速度，设计一种统筹方法优先处理故障数据，兼顾低优先级任务，同步控制各处理模块内部及模块接口任务逻辑切换，并留有一定的时间裕量，保证录波文件完整连续、录波数据精确可靠，实现故障录波系统多功能并行处理，达到了对电网进行长期有效监测的目的。

A High Accuracy and Real-time Synchronous Control Method for Fault Recording System

In view of the problems existing in China's fault recorders such as discontinuous recording data,single functions and difficult analysis,a fault recording and monitoring system based on multi-processor synchronous control is studied.The execution time of each processor and interface speed between modules are calculated.An overall planning method is given to process fault data with high priority while considering the task with lower priority at the same time.By synchronously controlling the logic switching b...
