usermat_CDM
These composite materials generally exhibit brittle damage behavior. The anisotropy in the
material and different kinds of failure mechanisms make it difficult to accurately
characterize the behavior of composite materials. The present work aims to verify and
apply the Puck Failure Criteria using the commercially available finite element package
ANSYS by writing a user-material subroutine in FORTRAN. The model is implemented
with different post failure degradation schemes EWM/CSE.

lcl滤波并网
说明： 并网逆变器通常采用L滤波器，虽然结构和控制简单，但是随着功率级别的增加会地带来体积重量增大等问题。LCL滤波器适用于功率较大的场合。(Grid-connected inverters usually use L filters. Although the structure and control are simple, problems such as volume and weight increase with the increase of power level. The LCL filter is suitable for occasions with large power.)

500KV双极
直流输电比起交流输电更适合进行远距离高压输电，基于PSCAD电磁暂态仿真软件构建了交流系统、换流变圧器、换流器、交-直流滤波器、平波电抗器及直流输电线路等的仿真模型，并以此搭建了500kV高压直流输电系统仿真模型，验证了该模型的准确性。(DC transmission is more suitable for long-distance transmission than AC transmission, the electromagnetic transient simulation software PSCAD is built based on the simulation model of AC system, converter transformer, voltage converter, AC / DC filter, smoothing reactor and DC transmission lines, and to build a 500kV HVDC system simulation model validation the accuracy of the model.)
