In order to strengthen the dynamic stability monitoring and analysis abilities of the power system, it is required to install the phasor measurement units (PMU) in the important substations and power plants, and build the wide area measurement system (WAMS). The phasor data concentrator (PDC) receives the synchrophasor data from PMUs, align the data with timestamps and output the concentrated data to the upper-level PDC or control center. PCS-996S-G is a substation PDC developed according to IEEE C37.118 standard. PCS-996S-G is usually used to concentrate synchrophasor data from multiple PMUs or IEDs which have integrated PMU function.
Receiving synchrophasor data from PMUs according to IEEE C37.118 Standard
Aligning synchrophasor data with timestamps
Configuring independent output data stream (CFG-2) for each super PDC through PDC assistant software
Outputting the concentrated synchrophasor data to the upper-level PDCs
Up to 20 PMU servers and 10 PDC clients are supported.
Receiving data rate: 2f0, f0, f0/2, f0/5(100/50/25/10 fps at 50Hz, 120/60/30/12 fps at 60Hz)
Outputting data rate: 2f0, f0, f0/2, f0/5(100/50/25/10 fps at 50Hz, 120/60/30/12 fps at 60Hz)
Supported communication protocols: TCP, TCP-UDP, UDP(Unicast/Broadcast/Multicast)
