大型风电场接入对交直流并行输电系统频率影响研究
The influence of large-scale wind farm connection on the frequency of AC/DC parallel transmission system
摘要
Abstract
This paper investigates the output conditions of delivering large-scale wind-thermal combined generation by AC-DC parallel transmission systems , a two-area system with four generators , large-scale wind farms and HVDC line between area 1 and area 2 was built up in PSCAD/EMTDC.Simulations were carried out under the circumstances of using wind energy to replace thermal power , and the results showed that the capability of frequency control of the ther-mal power units were better than that of wind generators .Finally, automatic generation control ( AGC) was added to generator 2 in area 1, the AGC was designed taking into account both the AC line power changes and the DC transmis-sion line power changes , and the frequency characteristics of the system and its stability were improved .关键词
