摘要
高电压等级主变压器的110 kV及以上中性点接地方式不仅与主变压器的停送电操作有关,而且与主变压器运行状态有关,同时与系统的继电保护方面的要求密切相关。以某地区电网为例对其110 kV变电站中的主变中性点运行方式常见故障进行分析,并提出了预防措施,以期对同类型的110 kV变电所的安全运行有一定的参考价值。
The neutral point grounding method of 110 kV and above for high voltage level main transformers is not only related to the power outage and transmission operation of the main transformer,but also related to the operating status of the main transformer,and is closely related to the requirements of system relay protection.Taking a regional power grid as an example,this paper analyzes the common faults of the neutral point operation mode of the main transformer in its 110 kV substation,and proposes preventive measures,with a view to providing some reference value for the safe operation of the same type of 110 kV substation.
