And for the abnormal judgment result, the intelligent wave recorder cannot issue a transmission command to the line protection equipment, and the lock issues the transmission command to the line protection equipment.
In the embodiment of the invention, in the process of judging whether the sampling value in the sampling state is in the allowable error range, the sampling value of the line protection equipment is compared with homologous data of other equipment, and the judgment result of sampling is considered to be normal if the obtained data is in the allowable error range, otherwise, the judgment result is abnormal. Comparing the homologous data of other equipment with the sampling value in the intelligent oscillograph firstly, and then comparing the homologous data of other equipment with the sampling value of another set of line protection equipment or other equipment; if the intelligent wave recorder is not provided with a sampling value, the 220kV protection can adopt a mode of comparing the sampling value with the sampling value of another set of line protection equipment, and the 110kV protection can adopt a mode of comparing the sampling value with the sampling value of other equipment (such as a measurement and control device). And for the abnormal judgment result, the intelligent wave recorder cannot issue a transmission command to the line protection equipment, and the lock issues the transmission command to the line protection equipment.
In the embodiment of the invention, in the process of comparing the consistency of the calling protection fixed value and the standard value in the fixed value state, the calling protection fixed value and the standard value which are called by the line protection equipment once are compared, if the calling protection fixed value and the standard value are completely consistent, the judgment result is normal, and if the calling protection fixed value and the standard value are not consistent, the judgment result is abnormal. And for the abnormal judgment result, the intelligent wave recorder cannot issue a transmission command to the line protection equipment, and the lock issues the transmission command to the line protection equipment.
The uninterrupted transmission operation detection method of the remote control intelligent recorder judges that the result is normal only if eight conditions, namely the operating state of the line protection equipment is normal, the sampling state is normal, the constant value state is normal, the pressing plate state is normal, the reclosing is fully charged, the remote operation hard pressing plate is put in, the overhaul hard pressing plate is withdrawn and the last transmission time interval exceeds 1 minute, and one condition is abnormal. And when the result is abnormal, the lock sends a transmission command to the line protection equipment, and the remote transmission operation is not allowed. The conditions of fully charged reclosure, remote operation hard pressure plate input and withdrawal of the overhaul hard pressure plate are judged when the protection receives a non-stop transmission command, but the operation safety is further ensured.
The non-stop transmission motion detection method of the remote control intelligent wave recorder can finish transmission condition pre-judgment in a remote place (namely the intelligent wave recorder), if all eight conditions are met, the judgment result is normal, and a transmission command can be issued, wherein if one condition is not met, the result is abnormal. And when the result is abnormal, the lock sends a transmission command to the line protection equipment, and the remote transmission operation is not allowed. The issued command is divided into two steps of selection and execution, the line protection equipment receives the transmission command, the line protection equipment also carries out self-checking to determine whether the transmission requirement is not cut off, the line protection equipment carries out execution according to the transmission command after the transmission requirement is met, and a reclosing outlet is carried out after the transmission tripping operation; the line protection equipment forbids to execute the transmission command and returns the transmission command to fail to execute when self-checking does not meet the transmission pre-condition without power outage, all signals in the transmission control process without power outage are sent to the intelligent wave recorder by the line protection equipment, and safety, reliability and visualization of remote transmission scheduled checking without power outage are improved. The uninterrupted transmission operation detection method of the remote control intelligent recorder also meets the requirements of the relay protection device and remote uninterrupted scheduled detection of the secondary circuit, and achieves the effects of synergy and load reduction.
The uninterrupted transmission operation detection device of the remote control intelligent wave recorder is communicated with the line protection equipment or the measurement and control device through the intelligent wave recorder through an IEC61850 standard communication protocol to obtain the information of position information, state information, voltage and current sampling, switching-in, pressing plate, fixed value and the like of the line protection equipment and the measurement and control device, and the intelligent wave recorder carries out prejudgment to confirm whether the line protection equipment has remote uninterrupted transmission conditions, if the intelligent recorder is provided with the remote uninterrupted transmission command, the line protection equipment is issued (if the intelligent recorder is not provided, the remote uninterrupted transmission command is automatically locked), so that the operation on the line protection equipment without the arrival of a maintainer on the site is really realized, the operation can be completed in a remote place only through an operator, the personal safety of the operation and maintenance maintainer is ensured, and the maintenance efficiency of the line protection equipment, the circuit breaker and other equipment is improved.
