World power

for the safe operation of power network in China there is hidden, the state approved immediate implementation of a special network security through implementation of the unit more than a year’s efforts, large-capacity, long-distance DC transmission grid stability and technological development made good progress.

high-capacity, long-distance DC transmission technology development is a combination of power system stability in southern China long-distance large-capacity AC-DC parallel grid characteristics, exist for the production of the actual impact of security and stability of the real problems develop with the applicable cross - stability analysis of parallel DC power-line technology, HVDC posture should be based on wide area of information technology, coordination and control, DC power over placement of the security and stability technology, for the protection of the South long-distance large-capacity AC-DC power grid safe and stable operation in parallel to provide technical means. Up to now, development projects completed on-line pre-decision analysis and overall system and test technology solutions and testing work is completed based on SCDMA / EMS system, the network dynamic equivalent program, completed the DC-3 Southern Power Grid real-time simulation of dynamic performance analysis, completed the Offline and online identification of the bulk power system, reduced-order technology development, as well as other relevant technical solutions and simulation testing of the contents of the whole, through research and development to obtain the safe operation of basic technologies and countermeasures program systems reliable, reasonable and feasible, but also has achieved good performance indicators for the safe operation of China Southern Power Grid to lay a foundation.
