Abstract: This application disclose a link configuration method, to configure a DSVPN tunnel interface parameter. A controller obtains a first link profile for a first site and a second link profile for a second site from a link profile library, where the link profile library includes a plurality of link profiles. The controller obtains preconfigured global configuration information, where the global configuration information includes an address pool. The controller generates a first link configuration parameter of the first site and a second link configuration parameter of the second site based on the address pool, the first link profile, and the second link profile and according to a preset link configuration rule. The controller sends the first link configuration parameter to the first site and sends the second link configuration parameter to the second site.

Abstract: A combined cooling, heating and power system is formed by integrating a CO2 cycle subsystem, an ORC cycle subsystem, and an LNG cold energy utilization subsystem based on an SOFC/GT hybrid power generation subsystem. The combined system can achieve efficient and cascade utilization of energy and low carbon dioxide emission. An SOFC/GT hybrid system is used as a prime mover. High-, medium-, and low-temperature waste heat of the system are recovered through CO2 and ORC cycles, respectively. Cold energy (for air conditioning and refrigeration), heat, power, natural gas, ice, and dry ice can be provided by using LNG as a cold source of the CO2 and ORC cycles. Low CO2 emission is achieved by condensation and separation of CO2 from flue gas, so energy loss of the system can be reduced, and efficient and cascade utilization of energy can be achieved, thereby realizing energy conservation and emission reduction.
