Study on Seismic Reliability of UHVDC Transmission Systems

Table 5

Reliability of different transmission capacity of a UHVDC transmission system after earthquake.

Transmission capacity	Reliability (%)	Transmission capacity	Reliability (%)
0	100	50%	92.929
12.5%	93.071	75%	54.270
25%	93.069	100%	53.951
37.5%	92.930	Expectation	73.56

Note: “Expectation” refers to the expectation of the residual transmission capacity after earthquake. The calculation process is detailed in Section 2.4.
