Research on the Frequency Dynamic Characteristics and UFLS Scheme in Shanghai Subzone Power Grid

Abstract:

Shanghai main power grid is operating in 500 kV ring network and with voltage-grading & district-dividing structure, and its subzone power grids have their own frequency characteristics. The paper has used district-dividing single equivalent model to check the parameters of components in BPA transient simulation program, and the original under frequency load shedding (UFLS) scheme was improved. Then the frequency dynamic characteristics of isolated subzone grid is analyzed, so does the adaptability and frequency safety of power grid under the new UFLS scheme in the condition of peak load in the summer of 2011.
