高地震烈度区换流站1000kV交流滤波器配电设备选型

1000kV ACF Switchgear Selection of Converter Stations in High Seismic Intensity Area

根据目前1 000kV特高压交流设备生产研发情况,从设备可靠性及投资经济性两个方面提出分层接入换流站1 000kV交流滤波器设备选型推荐方案,考虑该选型方案可能带来的抗震及电磁环境问题,利用有限元方法校核推荐的设备型式下配电装置的抗震性能及离地1.5 m处场强,校核结果显示,该选型方案能够满足规程要求的抗震要求及场强限值,证明了该方案的可行性。

In view of the current R＆D （research ＆ development） and manufacturing status, and concerning the reliability and economy, a scheme of 1 000 kV ACF equipment selection is proposed. The aseismic performance and field intensity at 1.5 meter above ground level are evaluated by using finite element method considering the aseismic and electromagnetic environment problems of proposed scheme. The result illustrates that the proposed scheme can meet the aseismic requirement and electric field intensity limit of relevant specifications. The feasibility of the recommended scheme is also demonstrated.
