Phasor Measurement
-
In order to improve the dynamic stability monitoring and analysis abilities, Phasor Measurement Units(PMUs) are installed in the corresponding substations and power plants. Furthermore, the use of a wide area measurement system(WAMS) serves to view the system’s state from the dispatching center. NR’s Phasor Measurement Unit(PMU) system is mainly applied to measure synchronized phasor and to record dynamic process of the power system.

PCS-997S Fault Line Locator
PCS-997S line fault locator is based on traveling wave fault location method and used for fault location of high voltage AC transmission lines. PCS-997S samples the current traveling wave signal of the fault line, exchanges information with the device on the other side of the line through Ethernet or dedicated fiber. The sampling rate of traveling wave is 2MHz, which enables a high fault location resolution of 75m. PCS-997S supports both single-ended and double-ended traveling wave fault location methods, and the typical fault location accuracy is better than 300m. PCS-997…

PCS-996S-G Phasor Data Concentrator
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 sy…
