老挝水电首经中老500千伏通道送达粤港澳大湾区_我的网站

A |     What better way to figure out a mystery of the ancients than to try it out yourself? That’s what one sailing aficionado from Israel did when confronted with a puzzle from the Christian Bible.,David Gal, a doctoral student in the Department of Maritime Civilizations at the University of Haifa, says he has figured out why the Christian Apostle Paul sailed from Judea to Rome along the southern coast of Anatolia in 60 CE - a route that, to him, wasn’t the most obvious one, since most winds in the Mediterranean are westerlies and Paul was going west.,That year, Paul was sent to the imperial capital to answer to Jewish authorities for preaching the teachings of Jesus of Nazareth, who claimed to have been the Jewish messiah. Most Jews did not accept Jesus’ teachings, and he was tried and executed by crucifixion for blasphemy and subversion in either 30 or 33 CE.,Paul’s journey is recounted in unusual detail in the New Testament book of Acts. The preacher zigzagged his way across the sea, swinging north of Cyprus before heading to the city of Myra (modern Demre) in southern Anatolia. From there, he went west past Rhodes, to Knidos, then south to the southern coast of Crete and west across the southernmost parts of the Ionian Sea. However, he was shipwrecked in Malta and his journey took much longer than anticipated.,“Until recently, we didn’t understand why the Alexandrian grain ship that Paul joined in southern Anatolia, bound for Rome, chose that particular route,” Gal told Haaretz.,The boat, Ma’agan Mikhael II, is a replica of a ship found in 1985 about 2 meters underneath the seabed off the coast of Kibbutz Ma’agan Mikhael in northern Israel, not far from Caesarea. In ancient times, the city was known as Caesarea Maritima or Caesarea Palestine, named after the Roman emperor Augustus Caesar. The replica boat was finished in 2016 and is just one of two ships in the world that simulates a merchant sailing vessel from Before the Common Era (BCE).,By coincidence, Caesarea also happens to be the port from which Paul left on his trip to Rome.,In part, Gal’s study was based on computer modeling, which combined vast amounts of weather data and conducted 5,479 virtual sailing trips along 224 different possible routes from Caesarea to Rome, for a total of 1.2 million virtual sailing trips. However, that wasn’t enough: Gal also took a crew of 10 volunteer sailors out in the Ma’agan Mikhael II to explore the intangible human element of the journey. With just one sail, the ship moves along at a brisk 3.9 miles per hour.,“Only when we sailed on Ma’agan Mikhael II did we understand the real limitations of the ship and the sailors,” Gal told Haaretz. “We found that in many sections of the coast, the breeze doesn’t support this type of movement.”,“They didn’t sail counter to the prevailing wind, but waited for days with a favorable wind in the opposite direction,” Gal concluded. “We found there were such days in a large meteorological sampling. Until now, scholars didn’t examine that but used low-resolution meteorological averages that erase the variance in the wind.”,Gal said he has taken the ship out more than 80 times, sailing as far as Cyprus, and found that the daily wind patterns, in which breezes can blow westward from the Levantine coast, have remained strong after 3,000 years. By navigating those patterns, ancient sailors could have crept up the coast until they found more favorable winds.,“We have data about its performance in all wind conditions and how various currents affect it, and that enables us to conduct a reliable simulation of sailing. With its help, we acquired insights into the way such a ship is operated; we had a better understanding of how four people can sail from Greece to here and back,” he said.。

C | 　　中老500千伏联网工程于4月20日正式投运，老挝北部清洁能源基地的光伏电能当日即通过该通道送入云南。此次老挝水电成功送达粤港澳大湾区，进一步拓宽了跨境清洁能源的消纳范围，推动形成“光伏+水电”互补的跨境清洁能源输送格局。　　南网澜湄国际公司市场交易部副总经理严明辉表示，2026年通过中老500千伏联网工程输送的光伏和水电参与市场化交易电量预计可达15亿千瓦时，下一步将持续发挥中老500千伏联网工程与“西电东送”大通道的协同效能，促进两国能源优势互补，提升澜湄区域能源资源配置效率，推进“一带一路”能源合作走深走实。

D | 　　据了解，中老电力联网合作已走过十余年历程。

E | 2009年，南方电网首次通过115千伏线路向老挝北部地区供电；2022年，中老双向电力贸易通过115千伏线路正式启动；中老500千伏联网工程投运后，两国电力合作正式迈入更高电压等级、更大输送规模的新阶段。
