摘要
110kV主变微机后备保护定值计算涉及到复压、方向及时间元件的配置和取舍,有较强的灵活性和技巧性,列举了案例,分析了使用这些元件的优缺点、存在的问题及解决方法和建议,论证了主变后备保护整定方案的合理性和可性性。
The coordination of 110 kV microprocessor-based transformer reserved protection implicate allocation and choice of complex voltage,direction and time,which contains enormous flexibility and skills. The merits and demerits,cause and solutions of using those items are analyzed. Through effective analysis and explanation,the solutions of 110 kV microprocessor-based transformer reserved protection are rational and practicable.
