| titleOfInvention | Power grid transmission quality evaluation method based on phase compensation amplitude subtraction |
| abstract | The invention based on the phase compensation amplitude subtraction power grid transmission quality evaluation method belongs to the fields of electric power system and the like; firstly, the phase angle range of each segment is calculated, and the flag generator, the first time recorder and the first transformer work synchronously. , the controller obtains the original phase information of the power plant signal through the differential output, and calculates the segment where the original phase of the power plant signal is located. Judging the positive and negative of the third comparison output, according to the table look-up method and based on the subtraction rule to calculate the segment compensation parameters, then the controller judges the positive and negative of the first comparison output, the second comparison output and the third comparison output, and calculates the power plant signal passing through. The phase after the power grid transmission is located in the segment, and finally the grid transmission quality is judged according to the consecutive segments; the invention can not only be used to evaluate the power grid transmission quality, but also can solve the problem of misjudgment caused by delay. |
