Abstract

The invention discloses a method for locating and sizing flexible alternating-current power transmission equipment. The method sequentially comprises the following steps of (1) drawing a curve 1, (2) drawing a curve 2, (3) drawing a curve 3 and (4) finding out a target value. The method has the beneficial effects that by comprehensively considering the power transmission capacity improvement effect of the power grid and the economic index of the flexible alternating-current power transmission equipment, the capacity of the flexible alternating-current power transmission equipment is fully exerted, and the power grid operation economic benefit is improved on the premise of meeting the safety and stability requirements of the power grid.

Description

Technical field: [0001] The patent of the invention relates to the technical field of site selection and capacity determination of power transmission equipment, in particular to a method for site selection and capacity determination of flexible AC power transmission equipment. Background technique: [0002] Since the birth of the concept of Flexible AC Transmission Technology (FACTS), FACTS technology has been extensively researched and rapidly promoted and applied. It is one of the fastest-growing and most influential emerging technology fields in the power industry in the past 30 years. At present, nearly 20 kinds of FACTS controllers have been invented, most of which have been commercialized and achieved good results, becoming one of the important technical means to solve many challenges of modern power grids. Making full use of the flexible adjustment capability and quick response characteristics of FACTS equipment can improve the security and stability of the power grid...
