摘要

在单机模型的基础上,研究了影响系统频率响应的关键因素,推导了大扰动后初始频率变化率和最大频率偏差的表达式,分析了提高常规机组频率稳定性和新能源频率响应、直流调频、负载频率响应、应急控制等因素的机理。根据西南电网的频率响应特点,从高频发电机跳闸对象、启动阈值、发电机跳闸容量等方面设计了超频发电机跳闸方案,提出了高周期发电机跳闸、发电机超速保护和低频减载的协调原则。通过实例验证了该方案的有效性。

Frequency Characteristics of Southwest Power Grid and Scheme of Over-Frequency Generator Tripping
Based on the single machine model, the key factors affecting the frequency response of the system are studied, the expressions of the initial frequency change rate and the maximum frequency deviation after large disturbance are derived, and the mechanism of improving the frequency stability of conventional units and new energy frequency response, DC frequency modulation, load frequency response, emergency control and other factors is analyzed. According to the frequency response characteristics of Southwest Power Grid, the over-frequency generator tripping scheme is designed from the aspects of high frequency generator tripping object, starting threshold, generator tripping capacity, etc., and the coordination principle of high cycle generator tripping, generator overspeed protection and low frequency load shedding is proposed. The effectiveness of the proposed scheme is verified by practical examples.
