Two Factors Promote the Development of UHV AC

According to the current situation, the Jindongnan-Nanyang-Jingmen UHV AC expansion project has entered the sprint phase, and the test operation is in good condition. Successful completion of important tests such as 5 million kilowatts of heavy load operation is a high-probability event, which will effectively prove the actual UHV exchanges. The transmission capacity injects a cardiac agent for the development of UHV AC. On the other hand, the problem of power shortage is difficult to eradicate in the short term, and the pressure for access to renewable energy is increasing. These issues require UHV exchanges to solve. We expect that UHV exchanges are expected to make progress in 2012 with the promotion of the above two factors. Distribution network construction will become the focus of power grid construction during the “12th Five-Year Plan” period, and the total investment statistics will reach 800 billion, including rural The transformation has risen to the national strategic height and is the highlight of distribution network construction. Due to the large number of early debts, the distribution automation and amorphous alloy transformer market is expected to fully benefit from the new round of distribution network construction.

Secondary equipment is the cornerstone of smart grid construction. From the previous trend, secondary equipment is better than primary equipment. The “Twelfth Five-Year Plan” is the second stage of smart grid construction. The investment in intelligent construction is 90% higher than the first stage. Under the impetus of multiple factors such as intelligent substation monitoring and protection, distribution automation, and telecontrol communication construction, etc. We are still optimistic about the prospect of secondary equipment.

Power Electronics has entered the era of upstream technological breakthroughs, midstream import substitution, and downstream field expansion.
