Power System Stabilizer Tuning to Eliminate Antiregulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for optimizing the antiregulation effect of power system stabilizers are inefficient and difficult due to varying parameter settings by different manufacturers, leading to inconsistent and suboptimal performance in suppressing power oscillations.
Innovation Solution
A method involving parameter analysis, division into fixed and regulable parts, and a voltage step test to determine and adjust specific parameters in the power system stabilizer to eliminate antiregulation effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parameter adjustment methods are used to reduce antiregulation effect, then the antiregulation effect can be improved, but the test efficiency is low and time-consuming due to the large number of parameters to be adjusted
Solution Approach 1:
The patent segments the stabilizer parameters into two distinct categories: regulable parameters (Ks1, Tw1, Tw2, Tw3, Tw4, Ks2, T7, Ks3, T8, T9, M, N) that directly influence antiregulation effect, and fixed parameters that remain unchanged. This segmentation allows testers to focus adjustment efforts only on the regulable parameters, significantly reducing the search space and improving test efficiency while maintaining the ability to achieve the desired antiregulation effect.
2Adaptability or versatility
If different manufacturers use varying parameter settings for standard power system stabilizer models, then device adaptability is improved, but manufacturing precision and consistency deteriorate
Solution Approach 1:
The patent establishes standardized parameter settings and adjustment ranges for the regulable parameters (Ks1, Tw1, Tw2, Tw3, Tw4, Ks2, T7, Ks3, T8, T9, M, N) that manufacturers can adopt. This standardization ensures consistent and precise parameter configuration across different manufacturers while still allowing flexibility within the specified ranges to adapt to specific system requirements, thereby resolving the contradiction between adaptability and manufacturing precision.

AI summary
A method for rapidly optimizing an antiregulation effect of a power system stabilizer includes: Step 1, deriving specific parameters influencing the antiregulation effect of the power system stabilizer; Step 2, dividing the specific parameters influencing the antiregulation effect of the power system stabilizer into a fixed part and a regulable part; and Step3, performing a step of a voltage at a generator end for the regulable part influencing the antiregulation effect of the power system stabilizer, determining whether a numerical value of a set node after the step falls within a set range, further determining whether antiregulation exists in two channels of rotational speed w and power p of the power system stabilizer, regulating, in a case that the antiregulation exists, the regulable part, causing the numerical value of the set node to fall within the set range, and causing the antiregulation to disappear.
