电力系统潮流解算中纵向调节和横向调节的处理

TREATMENT OF LONGITUDINAL AND TRANSVERSAL REGULATIONS IN POWER FLOW CALCULATION

本文在揭示纵向调节和横向调节共同性质的基础上提出了电力系统潮流解算中纵向调节和横向调节的统一处理方法。该方法给出了简捷地处理纵、横向调节的统一公式,它能方便地应用于各种类型的纵向及横向调节器(包括升压器和移相器),且容易与任何类型的潮流算法相结合。文中指出,在计及纵向或横向调节时,不能仅依靠潮流收敛判据采判断结果的准确性,而应给出具体的校核措施。文中还讨论了考虑调节器本身损耗的问题。实例分析表明,本文方法为进一步研究和推广应用纵、横调节器提供了一种有效的计算工具。

On the basis of explaining the common character of longitudinal and transversal regulations, this paper propases a unified method for them in power flow calculation. This method gives the simple unified formula of longitudinal and transversal regulations, which is suitable for various longitudinal and transversal regulations (including booster transformer and phase shifter) , and is easily joined with usual power flow algorithm. This paper also points out that determination of the result accuracy must be done with spc- cific checking measures instead of only with the convergence criterion while considering longitudinal and transversal regulations. Moreover, this paper discusses the problem of considering the loss of regulator. Example analyses show that the method provides an effective tool for the study and application of longitudinal and transversal regulations.
