Analysis of Reactive Power Voltage Characteristic for Huainan-Nanjing-Shanghai UHV AC Transmission Lines
摘要
Abstract
To understand the characteristics of reactive power voltage of AC UHV transmission lines,an equivalent system of Huainan-Nanjing-Shanghai UHV AC power flow was built by using the software BPA.The reactive power compensation degree and the reactive power balance for peak and valley were analyzed,the natural power and generalized natural power of the UHV AC transmission line at the boundary point between transmission capacity and reactive balance state were calculated,and the characteristics of voltage distribution along the UHV transmission line in different operating modes were also analyzed.Calculation results show that:①The reactive power compensation is adequate for both peak and valley requirements;②The generalized natural power accounts for about 28.65％～100％ of the natural power;③The maximum voltage amplitude appears between Taizhou Substation and Suzhou Substation and the voltage can be controlled within a reasonable range in five different operating modes.The reactive power resource allocation of Huainan-Nanjing-Shanghai UHV AC power transmission project can meet its requirement for safe and stable operation.关键词
