The PCS-9799 Station Manager is designed for the highest standards of performance, safety and reliability to meet requirements of a complex substation automation system (SAS). As a part of the SAS, it works as a station communication manager, which collects, stores and maps signals of relays, measurement units, control units and other IEDs in the substation to higher- level systems such as control center (CC) and distributed control system (DCS).
The PCS-9799 supports several protocols, such as IEC 61850 client, IEC 60870-5-101/104, NR private 103, IEC 60870-5-103 and CDT. These protocols form a standard protocol package to satisfy most requirements. Data can be transmitted to and received from analog channel, digital channel or network connected to CC, DCS or other system. The direct transmission mode and the device independent avoid any interaction or influence with the the substation SCADA (Supervisory Control And Data Acquisition) system.
Furthermore, the PCS-9799 can runs as a data acquisition and logic treatment platform and provides various and flexible advanced function extensions.
Relay information acquisition
Through serial or Ethernet port, this device can communicate with protection relays to gather their information such as SOE records, tripping signals, supervision alarms, etc.
Measurement & control IED information acquisition
Through serial or Ethernet port, this device can communicate with measurement & control IEDs and intelligent meters to gather their information such as sampled values, binary status, energy metering signals, etc.
Auxiliary IED information acquisition
In addition, this device can gather information of other auxiliary devices, such as energy meter, which are useful or crucial for the operation and safety of substation.
Remote control center communication
This device can realize the communication with multiple remote control centers with different protocols. The mapping transmission tables for different centers can be customized independently.
The signal synthesis function is supported with the help of the configuration tool PCS-COMM. Logical and mathematics operation of data such as AND, OR, NOT, XOR, +, -, × and ÷ can be proceed for the transmission to remote control center.
Local binary output
Several output contacts are equipped with the optional IO module to realize logic output. These outputs are configurable through the auxiliary software.
Configurable LED indication
Several LEDs are equipped on the device HMI panel to indicate a binary signal, such as alarm, communication state, switchgear position, etc. Some of them are defined by default while the others are configurable in 3 colors (green, red and yellow) through the auxiliary software.
All device critical manipulations, such as remote control and setting modification, need a user authority check. The authority password is configurable via local LCD.
Command record and query
This device records all the commands and operations, which include control selection, control execution, regulation, setting modification selection, setting modification execution, signal reset, etc. All these records can be viewed and queried with filter.
History event record
This device automatically records the events during its service, which include self running state change, alarm from connected IED, communication failure alarm, etc.
Double device redundancy strategy
Several device redundancy strategies are supported. The 2 devices are completely electrically independent. Their power supplies, communication ports and programs run independently. The inter-device exchange is realized electrical and network connection.
Dispatching IP auto-switchover
For the uplink redundancy mode with 2 devices, master and slave can automatically switch the unique dispatching IP address to realize a communication switchover with CC or DCS.
Consistency IP for dual network
For the downlink dual network mode with 2 devices, master and slave communicate with substation IEDs in using the same substation network IP address.
This device supports several time synchronization formats, including IRIG-B, network SNTP, time message, etc. It can also synchronize the connected IED with time message to unify the time in one substation.
On-line maintenance and monitoring
This powerful function enables the engineer to monitor the running status of this device through network, including running information print, message display of Ethernet port and serial port, on-field configuration, database view, virtual measurement, file transmission, remote rebooting, etc. With all these advanced functions, the substation upgrade becomes convenient.
During service, the device keeps a full supervision on its software and hardware, once an abnormality is found, the device will be self-blocked to ensure no maloperation is conducted, meanwhile, an alarm will be sent out both digitally and hardware output as alarm. If the device is dual equipped, at this time, if the abnormal device is on-duty then it will not only block itself but also activate the backup device to take over all the tasks to ensure the substation is still running normally. Meanwhile, the storage memory is checked regularly. If the storage memory minimum threshold is reached, legacy data delete strategy will proceed automatically.
