NR’s disturbance recording solution is a multifunctional data acquisition system designed to deal with the data recording requirements of transmission or distribution power substations. It is implemented by Disturbance Fault Management & Recording(DFMR) System and disturbance fault recorders(DFRs).
PCS-996RC disturbance & fault recorder is mainly used for recording the dynamic fault process of power system. The DFR is composed of one control unit (PCS-996RC) and multiple acquisition units (PCS-996RA). The control unit is linked to the acquisition units via fiber optic cables in point-to-point communication mode.The control unit PCS-996RC is responsible for concentrating and monitoring of large array of quantities from different acquisition units.The acquisition unit PCS-996RA is responsible for sampling and synchronizing of analogue quantities and digi…More Info
The PCS-996R disturbance & fault recorder (DFR) is a multifunctional data acquisition system designed to address the data recording requirements of substations. It captures the curves of monitored quantities and aligns the values of different supervised objects to build disturbance records. The PCS-996R helps users simplify disturbance analysis by combining the discrete records in different protective relays.The disturbance & fault recording system architecture can be centralized or distributed based upon customers’ requests. DFRs can also be applied to a substation …More Info
The PCS-986 disturbance & fault recorders are designed to record electrical parameters of generator-transformer units and operation processes in the protection& control devices of power plants. The device adopts unit architecture so that hardware and software can be flexibly assembled and upgraded in the future.More Info
The Disturbance Fault Recording Management System (DFRMS) is designed to manage various Disturbance & Fault Recorders(DFRs) across the entire power system. It provides real-time monitoring and waveform analysis based on the information collected from each DFR. Operators in local substations are capable of modifying settings, viewing alarm information and analyzing waveforms. Brief information is available for retrieving on request. Short message (SMS) and Email reminding functions are integrated into this management system.The DFR Management System can be …More Info
