Method for compensating data propagation time differences in distributed system, e.g. for static converter control, comprising phases of module calibration to determine synchronization times and delaying module executions accordingly

摘要

In a distributed system control modules (S) are connected to a master processor (UC) and consist of high and low sub modules (HL) and (LL) connected by fibre optics (3). Differences in data propagation times arising in the bus (1) are compensated by measuring response times to each control module, determining synchronizing times and using them to delay the execution of orders at each module appropriately
