A kind of sampling control method and device of adaptive SV sampling and routine sampling

The present invention relates to the sampling control methods and device of a kind of adaptive SV sampling and routine sampling, belong to field of relay protection in power.Method is as follows: identification analog quantity sampling configuration；When SV is sampled, analog quantity sampling is carried out according to pulse per second (PPS), resampling conversion is carried out to sampled data, and handle analog channel quality；It when routine sampling, is sampled according to sampling pulse, and judges channel quality；According to sampled data sources discrimination sampling configuration, when SV is sampled, after obtaining sampled data and quality, coefficient processing is carried out to sampled data, is used for relay protective scheme after being converted to secondary data；When routine sampling, sampled data is secondary data, for data calculating and logical process.This method carries out advanced processing to data according to different sampling configurations, and compatibility is strong, and it is excessive to advantageously account for current intelligent substation relay protection products model, production and the problem of maintenance cost is high and heavy workload.
