冬天的天气会带来电线倒塌的危险

2021年11月15日

哥伦布,内. – 随着冬季的方法, Nebraska Public Power District (NPPD) wants to remind people of the dangers of 倒下的 powerlines.  

冬季风暴会给输电线带来一些不同的威胁,包括疾驰, 倒下的, 和浮动电线. 当强风迫使两根相邻的电线相互碰撞时,就会出现舞动导线, 哪个可能导致停机. Floating wires consist of power lines that have been broken and are blowing in the wind or are not long enough to contact the ground.  

“如果有人发现电线掉在地上或被风吹着, 他们应该远离该地区,并立即通知当地的电力供应商,NPPD能源交付副总裁阿特·威斯说. “Broken power lines can have an electrical charge and are very dangerous if not handled professionally. They not only carry an electrical charge but can electrically charge any objects they are touching or even the ground around where a broken powerline is laying.”

如果一根断了的电线横躺在道路上, 驾车人士不应试图越过该线或将其移离道路. 这可能会导致严重的伤害.  如果电线掉到司机的车上, 居住者应留在室内, 打电话求助, 然后等专业人员来切断电源. 因火警或其他紧急情况而被迫离开车辆, 走到你的车边缘,跳离车, 双脚着地,不要同时接触地面和车辆. 然后拖着脚离开这个区域.  

Some residents may want to use a generator or grill to power their house or cook during a power outage. 这些都不应该在一个封闭的区域内运行或操作, 比如车库, 以避免任何可能的一氧化碳中毒. 如果有发电机安装, 确保由有执照的专业人士操作,以确保安全.  

NPPD客户可拨打1 - 877 -问nppd或直接到 NPPD.com 报告停电或电线损坏.

什么时候确定利率?
NPPD费率每年进行审查, and any proposed rate changes are normally approved during NPPD’s December Board of Directors Meeting.

我这个月的账单会不会因为寒冷的天气和轮流停电而增加?
Most NPPD customers can expect to see a higher monthly electricity bill this month due to the recent cold weather event which caused customers to have higher usage.  A higher bill would not be the result of a rate increase however because the rates did not change.

我的NPPD利率全年都在变化吗?
当建议利率变动时, NPPD通常在12月的董事会会议期间设定和批准利率. 被批准的利率将从明年2月1日起生效.

The only other time NPPD’s rates change during the year is when the higher summer rates automatically go into effect for the months of June through September. 除了这个, any increase or decrease in your bill is likely tied to increased energy usage during severe cold or hot weather.

NPPD零售价格保持稳定,8年来总体没有增长.

How will February’s cold temperatures and rolling outages impact my rates in future years?
The financial impact of the most recent historic polar vortex events as it relates to rates are unclear at the present time. 许多因素, 包括未来天气的影响, 负荷的增长, and the cost to generate and deliver electricity will impact NPPD’s financial position and rates.

低温和轮流停电会如何影响我的每月账单?
简单地说,如果你用了比“正常”更多的电,你就会有更高的账单. 费率没有改变. 把它想象成一种价格稳定的燃料,每加仑的价格从不波动. 如果你需要经常加油的话, 这将需要更多的产品, 因此你的成本更高.

现在降低恒温器是否需要更多的能源和成本, 只是为了以后能重新找回温暖?
这是一个许多人听了多年的神话. 相反的信念, your system will operate for longer periods to recover and heat pump systems may switch to supplemental or auxiliary heat, 但如果挫折发生在至少几个小时内,整体能源消耗就会减少. 

NPPD operators at our control center handle increases and decreases in load and train for these situations. 操作人员称之为冷负荷效应. 当客户长时间停机后恢复服务时, 用电量可能会急剧增加,这必须加以解释. As motors begin to start when the load is energized and more equipment powers on than was previously when the customer was interrupted. 这意味着, 当多个客户同时出现故障时, operators need to consider the load when the circuit is restored can be higher than when it was interrupted. 电路中断的时间越长,冷负荷效应就越明显.

在最近的这件事上, homes were using heat so consistently during the day and the interruptions were short enough that there was no significant change in electricity usage when one circuit was brought back online and another was turned off. 在轮流停电期间, 当一组客户出现故障时, a new set of customers would betaken offline before the first group was returned to service. This helped ensure that there were no spikes in electricity usage that would have a negative impact on the generation and load balance. 

我可以联系谁来协助我的NPPD账单的支付安排, 或者援助机构的信息?
请致电1 - 877 -问nppd联系NPPD安排付款事宜.

Those in need should also contact NPPD at the above listed number for more information and a listing of 能源援助 从当地机构.

什么是滚动停电?
轮流停电, 也称为轮流中断, 控制, temporary interruptions of the electrical service directed by the 西南电力池(SPP). These outages can occur when electricity generating resources cannot meet the electricity demand in the region. NPPD and others must reduce demand in an amount directed by SPP and act upon this within minutes.

什么时候需要滚动停电?
轮流停电 are necessary as a last resort to maintain the reliability of the electrical grid system. SPP directs rotating outages when electricity generating resources cannot meet the electrical demand in the region. They rotate or roll to different systems and areas so we can all absorb a short outage at different times versus a long outage for one specific area.

最近的情况非常特殊,一连串的事件是前所未有的, 包括整个SPP地区历史上的低温, 缺乏风力发电, reduced amounts of natural gas because of frozen wells and sky rocking natural gas prices. 这是自SPP成立以来本地区从未出现过的情况.

为什么有些客户在断电前几乎没有得到通知?
就像爱游戏官网的许多零售和批发客户一样, NPPD几乎没有警告就收到了SPP的紧急通知, 这就要求爱游戏官网在几分钟内采取行动.

NPPD did our best in this emergent situation to communicate not only to our large industrial and residential retail customers, 但也有尽可能多的批发客户. 这是通过一份爱游戏官网稿完成的, 通过电子邮件, 在活动期间定期安排批发客户会议, 使用社交媒体. 不幸的是, with the short timeframe not all customers were able to be reached before some outages began.

We continue to evaluate and review the events of this situation and will look for ways to learn and improve our process, 它还会被再次需要吗.

有没有一种简单的方法来跟踪我的能源使用情况?
Tracking your energy usage can easily be done by downloading NPPD’s mobile application, “NPPD On The Go!”. 在谷歌Play或苹果应用商店搜索“NPPD”下载. Then click “Register” and have your account number, service address zip code, and phone number ready. 最后完成帐户信息.

使用NPPD的好处是什么!”?

  • 快速,简单和安全的方式查看和支付您的账单.
  • 查看每月的使用情况,并与以前的使用情况进行比较.
  • 监视活动中断并报告意外中断.
  • 通过移动设备直接访问客户支持.
  • 请求新的服务或停止当前服务.
  • 注册宕机、计费和使用通知.

什么是西南动力池(SPP)?
NPPD是 西南电力池(SPP), a non-profit regional transmission organization in the central part of the United States. SPP is mandated by the Federal Energy Regulatory Commission to ensure customers in the region receive reliable power, 充足的输电基础设施和价格有竞争力的电力. SPP及其成员协调超过65个国家的电力流动,跨越14个州的3000英里高压输电线路.

为什么拥有多样化的能源组合很重要?
NPPD相信多元化的世代组合是爱游戏官网客户最好的服务. 爱游戏官网利用风——当它可用的时候. 爱游戏官网使用煤炭,这是可靠的,有助于保持低电费. 爱游戏官网使用水——最古老的可再生能源之一. 爱游戏官网使用核能——它提供零排放、24小时不间断的电力. 爱游戏官网使用天然气来补充投资组合.

NPPD’s diverse energy generation mix helps keep our electricity reliable and keep rates as low as possible.

公共权力, 一如既往, answered the call to help protect the bulk electric system which serves the central portion of the country and is part of the larger Eastern Interconnect. 系统需要实时均衡生成和负载. In doing so, we also protected our customers from more detrimental, long-term blackouts.

在这一紧急事件中,所有NPPD的工厂都可以提供给SPP. They performed as beautifully during the emergency as our NPPD teammates who worked around the clock to manage the safety, 爱游戏官网客户的健康和财务风险.
