所谓的没联系，只是这个人的观点而已，根本没证据支持这个专家：
"My understanding, at least at the moment, is there's no evidence to suggest these two issues are related," Mr Wood said.
维基上对2016年的断电事故的分析描述很详细，极端天气并非唯一原因，还有其他技术问题在里面，但极端天气确实是主要的触发因素：
“The preliminary report from the Australian Energy Market Operator (AEMO) identified that problems started 90 seconds before the eventual failure. The first line to trip was a 66 kV line near Adelaide, and it was automatically reset. The first major fault was 47 seconds later when two phases of the 275 kV line between Brinkworth and Templers grounded. The Davenport–Belalie line tripped with one phase to ground, was automatically reset, but tripped again nine seconds later, so was isolated for manual inspection, with the fault estimated to be 42 km (26 mi) from Davenport. One second later (7 seconds before the state went dark), the Hallett Wind Farm reduced output by 123 MW. Four seconds later, a third 275 kV transmission line showed a fault, the Davenport–Mount Lock is on the other side of the same towers as Davenport–Belalie, and the fault was estimated to be 1 km (0.6 mi) further on. The damaged power lines caused 5–6 voltage glitches which stressed the ride-through capability of most of the wind farm capacity, causing nine of them to shut down:[10] Finally, all within one second, the Hornsdale Wind Farm reduced output by 86 MW, Snowtown Wind Farm reduced output by 106 MW, the Heywood interconnector flow increased to over 850 MW and both of its circuits tripped out due to the overload. Supply was then lost to the entire South Australian region of the National Electricity Market, as the Torrens Island Power Station, Ladbroke Grove Power Station, Murraylink interconnector and all remaining wind farms tripped.[11]
AEMO identified software settings in the wind farms that prevented repeated restarts once voltage or frequency events occurred too often. The group of wind turbines that could accept 9 ride-throughs in 120 seconds stayed on line through much of the event before the system went black. The rather larger group of turbines that could not accept this many repeated ride-throughs dropped out, instigating the overload and shutdown of the interconnector, and hence the electricity supply. AEMO has suggested better fault ride-through capability for the wind farms. The high wind speed caused 20 MW of wind power to disconnect to prevent overspeed.[10]
In 2019, the Australian Energy Regulator initiated proceedings in the Federal Court of Australia against the operators of four wind farms. It alleged that these companies had failed to comply with performance requirements to ride through major disruptions and disturbances. The companies AGL Energy, Neoen, Pacific Hydro and Tilt Renewables operated several of the large wind farms that tripped during the incident including Hallett,[12] Hornsdale, Clements Gap and Snowtown.”
如果这也叫没联系，就太忽悠人了吧。 |
