Embodiment Construction
[0089] The present invention will be further described below in conjunction with the accompanying drawings. The flow chart of the present invention is as figure 1 shown. Reliability requirements on frequency can be divided into safety requirements and adequacy requirements. Among them, security requirements on frequency can be further divided into short-term security requirements and long-term security requirements, respectively as figure 2 and image 3 shown. figure 2 Medium and short-term security requires that the frequency difference ΔF′ under disturbance exceeds the limit value ΔF m The continuous time cannot be longer than T m , where T m It is the power system that can continuously withstand the abnormal frequency difference ΔF m the longest time. image 3 Medium and long-term safety requirements, in a long period of time (such as one year), the frequency difference ΔF' under the disturbance exceeds the limit value ΔF m The cumulative time of can not be more...
