Embodiment Construction
[0127] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0128] See figure 1 , A voltage stability online monitoring phasor data measurement device, including a synchronous clock unit, an acquisition module, an input unit, a dual-port RAM transmission module, a data management unit and an output unit; among them,
[0129] The clock unit of the data management unit during synchronization is composed of GPS module, ARM7 synchronous sampling pulse conditioning module and 232 communication module. Among them, the ARM7 synchronous sampling pulse conditioning module adopts the ARM7 processor of LPC2132 chip. GPS module outputs equal interval synchronous sampling pulse signal and clock message signal, ARM7 synchronous sampling pulse conditioning module receives equal interval synchronous sampling pulse signal, and sends out A / D synchronous sampling signal to realize synchronous data sampling; 232 communication modul...
