The application and recent development of intellectual ground compensation and line - selector 智能接地补偿及选线装置的应用及发展
The paper discusses the influences of zero-sequence mutual inductance to ground distance compensation coefficients and zero-sequence zone I of current protection. In addition, it studies the ability of impedance relay standing the transition resistance, and finally puts forward a simplified method for operation of backup relay. 讨论了零序互感对接地距离补偿系数和零序保护Ⅰ段的影响,分析了阻抗继电器躲过渡电阻的问题,提出了后备保护简化配合的方法。
This paper has carried on deep analysis and studies to various kinds of capacitive current calculation methods of resonance ground system and compensation principles of arc-suppressing coil, and has pointed out the error that they exist in theory and the necessity of reducing the error. 本文对谐振接地系统的多种电容电流计算方法和消弧线圈补偿原理进行了深入的分析与研究,指出了它们在理论上存在的误差及减小误差的必要性。
In the process of industrialization and urbanization, the problem of Land acquisition and resettlement has been more prominent, especially that in relation to housing and other ground attachments relocation compensation. 在工业化和城镇化发展过程中,征地拆迁的问题一直较为突出,尤其是涉及房屋及其他地上附着物拆迁补偿的问题。
