摘要
以重庆电网2015年和2020年丰大方式数据为基础,针对大功率穿越重庆电网的特点,研究了准东—重庆1 000 kV特高压直流接入对重庆电网产生的影响。着重分析了正常负荷和高负荷方式下重庆电网在不同受电比例情况时系统的安全稳定情况.根据计算结果提出了适合重庆电网2015年和2020年安全稳定运行的受电比例,以及应加快特高压网架建设提高系统稳定性的建议。
Based on 2015 and 2020 flood season power flow mode of Chongqing grid, according to the characteristics of high power through condition, various receiving-end system stability effects of Zhundong--Chongqing 1 000 kV UHV DC access to Chongqing grid are analyzed. The system security stability situations of Chongqing grid are analyzed under normal and high load mode in different receiving power proportion. According to the calculation results, the receiving power proportion suitable for safe and stable operation in year 2015 and 2020 are proposed. It is also advised that speeding up UHV grid construction can improve the system stability.
