地区范围的中断
地区范围的中断 are typically caused by significant weather events. 在太平洋西北部, 最常见的区域性停电事件是由秋冬季的大风和暴风雪引起的, 但其他原因可能是地震, 洪水, 野火或其他自然灾害. 中断 may impact several thousand to several hundred thousand customers.
中断事件的开始
区域风暴基地和我们的紧急协调中心开放以支持船员和资源协调, response strategy and internal and external communication.
评估损失
As soon as conditions allow and it’s safe to begin field activities, our damage assessors drive to reported outage locations across our service area to:
- 识别潜在的安全隐患(例如.g.(电线倒下)
- Gain visibility of the damage and assess severity
- 向区域风暴基地报告恢复电力所需人员和设备类型的详细信息
损坏评估也是帮助我们为客户估算修复时间的关键步骤. 在区域性停电事件中，损失评估可能需要数天才能完全完成.
建立风暴应变计划
风暴基地和紧急协调中心使用来自损害评估人员的信息来确定所需的资源, outage restoration prioritization and other response strategies.
中断恢复优先级
- 第一个, repair crews focus on restoring power to essential services such as hospitals, 水/废水系统, 和运输. 优先电力恢复也适用于向变电站供电的高压输电线路，这些变电站为广大地理区域内的大量客户提供电力.
- 下一个, 工作人员集中精力修复被损坏的配电和服务线路，这些线路直接为家庭和企业服务.
- 随着我们对情况的不断了解和对新出现的问题的响应，中断恢复的优先级也在不断变化.
恢复工作继续进行
我们的工作人员和停电响应人员夜以继日地工作，直到所有客户的电力恢复.
How does PSE estimate when my power will be restored?
每个区域范围的中断事件都是独一无二的, 和估计恢复时间(ETRs)是基于以下因素制定的:预测停电地点的数量, 损伤严重程度, 资源分配, 活跃的天气和通道挑战. 当我们的现场团队获得地面可见性时，我们在中断图上添加并更新ETRs. 有时, more system damage can occur due to ongoing active weather, ETRs可能需要更新. ETRs一般分为三个阶段:
- ETR待定(待定):在区域范围的中断事件期间, we don’t add ETRs to the outage map until damage assessment is well underway. 建立ETRs所需的时间因现场条件和事件的严重程度而异. In large outage events, it can take 24–48 hours to establish regional ETRs.
- 区域ETR: The date/time we expect most customers in a given region to have their power restored. Many customers will be restored sooner than the regional ETR; some customers may have their power restored after. While regional ETRs are not specific to individual 中断, they are general timeframes for restoration that help our customers plan. 我们努力在大规模停电事件的前24-48小时内共享区域ETRs.
- 停机-specific ETR当我们有足够的现场能见度和指定的工作人员来恢复您的电力时，将建立由我们现场人员提供的特定于停电的ETRs. 有时，根据维修期间收集的其他信息更新特定于中断的ETRs.
We understand ETR information is important so our customers can plan. Please know we work to provide the most accurate information as quickly as possible, and we thank you for your patience as we move through the process.
当地的中断
局部中断是指在区域范围的风暴或紧急事件之外发生的日常中断. They may be the result of a tree coming into contact with a power line, 电气设备故障, 或者一辆车撞上电线杆.
初始ETR设置
在客户报告中断后, PSE’s System Operations team provides an initial estimated time of restoration (ETR), 对电力恢复时间的估计, 基于历史停机数据.
Restoration through 配电自动化
In many locations across PSE’s service area, power can be restored through 配电自动化 (DA) – often referred to as a “self-healing grid.” If an outage occurs on a DA-enabled distribution line, 我们可以自动隔离停电的来源，并迅速恢复所有没有直接服务于电力线受损部分的客户的电力. 这意味着我们可以减少受停电影响的客户数量，并更快地恢复供电.
评估损失
PSE的电气第一反应小组到达停电地点，评估现场情况，确保现场电气安全. 第一个 responders may restore power to some or all remaining customers, depending on the location and severity of the damage.
人员分配
If our first responders identify the need for additional repairs, an electric crew from our service partner Potelco, 公司. 谁被派去修理. They will replace a pole, re-string electrical wire, or replace damaged transformers.
ETR更新
估计恢复时间(ETR)信息会随着更多信息的可用而更新, based on field conditions and 损伤严重程度.
How does PSE estimate when my power will be restored?
When an outage occurs on a typical “blue sky” day, 估计恢复时间(ETR), 对电力恢复时间的估计, is provided automatically 基于历史停机数据.
As our field teams assess damage in the field, we update the ETR based on field conditions and 损伤严重程度. 如果停电需要我们从线路上移走一根树枝，可能需要30分钟才能恢复, 如果停电需要更换电线杆，维修人员到现场后可能需要4-6小时才能恢复. 您在中断图上看到的ETR是我们当时对您的特定中断的最佳估计, and we’ll provide ETR更新 as needed until power is restored.
We understand ETR information is important so our customers can plan. Please know we work to provide the most accurate information as quickly as possible, and we thank you for your patience as we move through the process.
A 公共 安全 Power Shutoff (PSPS) outage, which includes the duration of the weather event and restoration time, could last several days if damaging winds occur.
检查
Once the high-risk weather conditions have subsided, 在恢复供电之前，工作人员将目视检查输电线是否有损坏或安全问题. PSE will work to safely restore power as quickly as possible, but there can be challenges if there is limited access or visibility, 或者附近的活火.
恢复阶段
天气“晴朗”: 天气过去且安全后，船员开始进行海上巡逻和检查.
巡视和检查: 工作人员目视检查线路、电线杆和其他设备的潜在天气损坏情况.
隔离和修复损坏: 在哪里发现设备损坏, 工作人员将受损区域与系统的其余部分隔离开来，并恢复未被损坏设备服务的客户. 然后工作人员将进行必要的维修.
恢复供电: 一旦修复完成且安全，PSE将恢复向客户供电.
估计恢复时间(ETRs)
As our field teams gain boots-on-the-ground visibility, we will add and update ETRs on the outage map.
- 区域ETR: The date/time we expect most customers in a larger region to have their power restored. Some customers will be restored sooner than the regional ETR, while other customers may have their power restored after.
- 字段ETR: 一旦线路巡逻完成，由我们的现场人员提供，并在工作人员进行任何必要的维修时更新.
停机恢复常见问题
为什么我的邻居有权力，而我没有?
在中断期间, one part of a neighborhood may have its lights on while another remains without power. Because our electric system works in sections or circuits, one circuit may have power while another may not.
另外, PSE crews can re-route power around damaged areas on a circuit, thereby isolating the section that requires repairs. 在这种情况下，电路服务的一些客户可能有电，而另一些客户可能没有.
你也可能损坏了你的服务线路——从你家到附近配电线路的线路.
我在我的区域没看到任何船员. 他们在哪里??
Crews are most likely working on repairs at another nearby site. 如果有大面积的损伤, 在你所在地区的电力恢复之前，电力系统上可能有多个区域的设备需要修理或更换.
Why did a crew come to my neighborhood and leave without restoring power?
您可能会看到您附近的现场工作人员正在为我们的电气人员完成修复工作做准备. 维修前, 损坏评估小组找出损坏的来源，并确定需要维修的设备. 另外, 树木工人可能需要清除树木或植被，以便我们的电力工人能够进入维修地点. The last step is for our electric crews to complete repairs and restore power.
What should I do if I see a power line on the ground?
Assume all downed utility wires are energized and stay as far away as you can. If you see a downed wire, call 911 or PSE at 1-888-225-5773. Leave everything to qualified electrical utility professionals and emergency personnel.
不要在倒下的电线上开车. They can get entangled with your vehicle and cause further damage. If a power line falls on your car while you’re driving, stay in your car! 在线路被合格的电气专业人员确认断电之前，不要试图下车.
停电时如何保证安全?
- Do not use a charcoal or gas grill to cook indoors. Never use a natural gas range for heating, or charcoal as an indoor heating source. This can cause a buildup of poisonous carbon monoxide gas.
- If you choose to use a portable home generator, read the manufacturer’s instructions for the safe operation of the generator. 不要在室内或封闭空间操作发电机，以免一氧化碳积聚.
- 如果你用的是便携式加热器, 让它们远离家具, 窗帘和其他易燃材料.
- 一定要用手电筒而不是蜡烛.
How can I keep the food in my fridge and freezer cold during a power outage?
- Keep freezer and refrigerator doors closed; open them only when necessary. 如果你把冰箱的门关好，食物可以在装满食物的冰箱里冷冻36 - 48小时. A half-full freezer will generally keep food frozen for 24 hours.
- 访问美国农业部的网站并阅读 在紧急情况下保证食品安全.
