The invention discloses a primary
frequency modulation and
inertia response online measurement and
control system which comprises a
wide area measurement
system WAMS, a measurement and control
master station, a measurement and control substation, a
phasor measurement unit PMU and a primary
frequency modulation /
inertia response control system. The test substation transmits parameter setting data of the measurement and control main
station to the primary
frequency modulation /
inertia response control system, generates a simulated
power grid typical working condition
voltage signal according to an instruction of the measurement and control main
station, and accesses the simulated
power grid typical working condition
voltage signal to the primary frequency modulation / inertia
response control system; the primary frequency modulation / inertia response
control system calculates to obtain a tested frequency
signal and a frequency change rate and responds to the tested frequency signal and the frequency change rate; after a
phasor measurement unit (PMU) calculates and obtains the active power of a grid-connected point and the amplitude, the phase, the frequency and the frequency change rate of the output
voltage of a measurement and control substation, the active power and the amplitude, the phase, the frequency and the frequency change rate of the output voltage of the measurement and control substation are transmitted to a
wide area measurement system (WAMS), the
wide area measurement system (WAMS) packages and sends the packages to a measurement and control
master station, and the measurement and control
master station carries out primary frequency modulation and inertia response function and performance evaluation and PMU measurement performance
test analysis.
