Due to the rapid development of intelligent substation, the communication network message of substation station control layer, interval layer and process layer has become a major way of information interaction and sharing among intelligent substation devices. The condition of smart devices and communication network will directly affect the communication of the whole smart substation. Any problems at the sender, receiver or communication network could lead to major accidents in power system, so it is necessary to monitor, record and diagnose network message, find network weakness and faulty equipment in advance. When the power system fault occurs, not only the original network message needs to be recorded, but also the network message needs to be analyzed and recovered as fault waveform of primary side equipment and action records of secondary side equipment, so as to analyze and quickly find the fault cause after the accident.
GDPA-61850 Portable Analog-digital Wave Record Analyzer (hereinafter referred to as GDPA-61850) can be directly accessed to DL/T 860-9-2, GOOSE and IEEE 1588 time synchronization message of process layer of intelligent substation network, when power system fails, fault wave recording is started, record waveform of primary voltage and current of the system and the action of secondary equipment, realize power system fault analysis and fault location. GdPA-61850 also has the function of continuous data recording, which continuously records the data related to the electrical quantity of the power system, and marks the disturbance characteristics on the continuously recorded data according to the built-in criterion, so as to facilitate the disturbance data retrieval.
The communication between GDPA-61850 and station control layer equipment adopts IEC61850 MMS communication protocol to realize the inter-operation with station control layer equipment.
GDPA-61850 is a fault recording and analysis device for the process layer network of smart substations. It has the functions of condition monitoring, early warning and fault analysis of the secondary network system and primary system of smart substations. It is widely used in smart substations and provides reference for the safe and reliable operation and management of smart substations.

1. Acquisition unit
The acquisition unit can work independently and has the functions of data acquisition, analysis and processing, anomaly judgement, fault analysis, data recording and data remote transmission.
The acquisition unit is directly connected to the process layer network and/or station control layer network of the substation, receives all messages from the process layer network and/or station control layer network (process layer network messages mainly include SMV, GOOSE, GMRP, PTP, etc.). Network messages of station control layer mainly include MMS, TCP/IP, UDP/IP, NTP/SNTP, FTP, ARP, ICMG, IGMP, etc.), and these messages are decoded and analyzed in real time to check for various abnormal states such as frame loss, wrong order, out of step, timeout, interruption, invalid encoding, traffic mutation, etc., and abnormal event warnings are given in real time. When the original message storage module is configured, the original message data can be in cyclic storage, and can be read and analyzed at any time on the management interface according to the event label.
The acquisition unit is also responsible for the acquisition and recording of the switch and analog quantities of circuit breakers, disconnecting switches and relay protection on each side of the circuit and the main transformer, fault starting discrimination, signal conversion and other functions.
The acquisition unit runs on the embedded real-time operating system, which can be configured with up to 2 2.5-inch SATA ports at the same time, can support hard compression, and can effectively store data up to 2TB+.
