SF_6/N_2混合气体应用的综合评价模型
|
摘要
SF_6/N_2混合绝缘气体因其液化温度低、电气性能好、环保及价格低等优点,被认为是目前最具发展前景的SF_6替代介质。但SF_6/N_2混合气体应用的综合评价问题尚缺乏研究。文中从电气性能、环境影响及成本三方面入手,构建了SF_6/N_2混合气体应用的综合评价模型。考虑混合气体各方面约束,提出采用电气性能目标最大化、环境影响目标及成本目标最小化的气体压力与SF_6应用比例求解方法。结果表明:提出的SF_6/N_2混合气体应用的综合评价模型可实现电气性能、环境影响及成本多目标的综合考虑,尤其是环境温度对气体压力与SF_6应用比例的影响,能够有效提升混合气体GIL工程应用的环保性、安全性和可靠性。
SF_6/N_2 gas mixtureis regarded as one of the most promising alternative insulating gases to SF_6 because of its advantages such as low liquefaction temperature,nice electrical performance,good environmental protection and low price. This paper considers electrical performance,environmental impact and cost to build a multi-objective optimization comprehensive evaluation model of SF_6/N_2 gas mixturefor engineering application.Considering all aspects of the constraints of the gasmixture,a method for solving the gas pressure and SF_6 application ratio toward maximizing electrical performance objective and minimizing environmental impact and cost objectivesis proposed.The results show that the proposed evaluation model of SF_6/N_2 gas mixture application can comprehensively consider electrical performance,environmental impact and cost,especially the influence of ambient temperature on the gas pressure and the SF_6 application ratio. This study mayeffectively facilitate environmental protection,safety and reliability of the GIL in engineering application.
