摘　　要：随着新能源快速发展,大规模新能源场站接入电网,在继电保护可靠性和对电压及频率控制方面都存在巨大风险与挑战。新能源场站稳定可靠运行是保证电网安全的基础,但由于新能源场站建设速度快、周期短,导致专业人员短缺而出现部分继电保护定值整定不规范、不合理的情况,使新能源场站运行存在较严重的缺陷。针对电气系统设计及继电保护定值的问题进行分析并处理,解决了缺陷带来的安全隐患,提高了新能源场站继电保护装置运行的可靠性。With the rapid development of new energy and the access of large-scale new energy stations,there are risks and challenges in the reliability of relay protection and the control of voltage and frequency.The stable and reliable operation of new energy stations is the basis for ensuring the safety of the power grid.However,due to the rapid construction speed and short construction period of the new energy station,there are the shortage of professional personnel being caused by the overall non-standard and unreasonable setting of partial relay protection and still serious defects in the new energy station after the operation and production.It analyzes and deals with the typical problems of electrical system design and relay protection setting value.It solves the safety risks caused by defects and improves the reliability of the new energy station relay protection device.
