摘要： A measurement data based method for identifying wind turbine generators which cause sub-synchronous oscillations in a complex power system has a theoretical foundation of the open-loop modal resonance and the parallel filter design. The advantages of the present invention are as follows. 1) The present invention can identify the wind turbine generators which cause the SSOs in the complex power system using measurement data instead of parametric model. Hence, it simplifies the computation and reduces the modeling cost effectively. 2) The present invention can identify the wind turbine generators which cause the SSOs in the complex power system precisely with reduced amount of measurement data, reducing the cost of hardware and data measurement effectively. 3) The present invention can identify the wind turbine generators which cause the SSOs in the complex power system based on the open-loop modal resonance theory.

摘要： To obtain a digital signal representative of the average value of the frequency of a V.C.O. 11, a monostable is used to produce fixed length pulses at an indeterminate frequency. These pulses are counted by a control counter and enable a gate to pass the V.C.O. output to a counter connected as a frequency divider. Both of these counters are preset with the same count state and the "borrow" outputs from the dividing counter are counted in a signal counter, the number of "borrow" pulses received in the time taken for the control counter to count to its preset state being the required digital signal.
