Abstract:
With the introduction of high proportion renewable energy and high proportion power electronic equipment into the power grid, the demand for wide-frequency observability and measurability is becoming increasingly urgent. It is urgent to establish a set of wide-frequency measurement device suitable for power system. On the basis of investigating the domestic recent research situation, the scientific problems of wide-frequency unifying high precision measurement are expounded, focusing on the engineering and technical problems encountered in the current wide-frequency measurement. The research idea and framework of power system wide-frequency measurement technology are proposed from five aspects: high-precision acquisition of multi-component signals, accurate identification of instant, transient and steady-state signals, highly efficient transmission of signal measurement and analysis results, wide-frequency testing technology and testing platform, regulation mode and regulation effect monitoring. At the same time, wide-frequency measurement device is developed on the basis of phasor measurement unit. The implementation effect of the technology is preliminarily verified and the key research directions of the follow-up research are pointed out.
Key words:  wide-frequency measurement  high precision acquisition  measurement algorithm  test calibration
