數(shù)據(jù)中心運營商和應(yīng)用程序所有者需要運行大量服務(wù)器和耗電設(shè)備，同時優(yōu)化功耗。配電單元 (PDU) 用于控制和分配各種設(shè)備的電力。如今，由于遠程監(jiān)控需求的增加，具有遠程測量和切換功能的智能 PDU 的市場增長顯著。

事實上，近的一份報告指出，對數(shù)據(jù)中心監(jiān)控解決方案不斷增長的需求是 PDU 市場增長的關(guān)鍵驅(qū)動力。監(jiān)控應(yīng)用程序中的 PDU 不僅有助于優(yōu)化能源使用，通過記錄用于支付計算和能源管理的每日功耗，還允許收集有關(guān) PDU 狀態(tài)的數(shù)據(jù)以進行設(shè)備維護。

根據(jù) Moxa 的說法，要獲得監(jiān)控 PDU 的好處，能源管理系統(tǒng) (EMS) 需要從 PDU 收集儀表數(shù)據(jù)，以便操作員可以控制、監(jiān)控和優(yōu)化 PDU 的性能。此外，遠程配電板（RPP）也可以作為PDU的擴展，通過提供額外的電路來增加配電容量。因此，監(jiān)控斷路器和電流互感器以確保通過不同電路的配電受到控制也很重要。

它需要 EMS 和電力設(shè)備（如 PDU 和 RPP）之間的可靠連接，以確保平穩(wěn)和優(yōu)化的電力分配。以下是確保兩者之間可靠連接的提示。



 

一旦用戶決定在應(yīng)用環(huán)境中監(jiān)控 PDU 和 RPP，啟用連接的問題取決于實施計劃。除了連接可能使用與您的 EMS 不同的協(xié)議和接口的電表、斷路器和電流互感器之外，請詢問以下問題。

目標是改造現(xiàn)有 PDU 還是部署新 PDU？是否有足夠的布線設(shè)計空間？有多少 PDU 將連接到網(wǎng)絡(luò)？

對上述問題的回答將揭示對單端口或高端口密度連接解決方??案的需求。例如，如果您在相對小規(guī)模的應(yīng)用中改造現(xiàn)有 PDU 的空間有限，那么單端口連接解決方??案可能是理想的選擇，因為它設(shè)計緊湊。相比之下，如果有足夠的空間來部署多個新的 PDU，高端口密度連接解決方??案可以幫助節(jié)省成本。

選擇易于使用的連接解決方??案可以節(jié)省大量時間和精力。在安裝階段，當(dāng)您將數(shù)十個 PDU 連接到同一個網(wǎng)絡(luò)時，布線可能會很痛苦。檢查所選的連接解決方??案是否具有以太網(wǎng)級聯(lián)等功能，它為位于控制中心的 EMS 提供跨多個 PDU 和 RPP 的高效布線解決方案。當(dāng) PDU 和 RPP 啟動并運行時，網(wǎng)絡(luò)設(shè)備仍需要不時進行備份和更新。

當(dāng)發(fā)生意外的網(wǎng)絡(luò)故障時，電表數(shù)據(jù)丟失可能導(dǎo)致功耗數(shù)據(jù)計算錯誤，從而導(dǎo)致計費錯誤和用于分析的電力數(shù)據(jù)不完整。為了提高電力監(jiān)控系統(tǒng)的可靠性，從不同的角度考慮備份機制。從網(wǎng)絡(luò)設(shè)備開始。

雙電源輸入和高 EMI 抗擾度是可以保護網(wǎng)絡(luò)設(shè)備免受電氣干擾的特性。其次，開發(fā)網(wǎng)絡(luò)傳輸?shù)娜哂鄼C制。市場上有各種網(wǎng)絡(luò)冗余功能。在考慮這些選項時，請查看它們的恢復(fù)時間是否可以滿足電源監(jiān)控應(yīng)用的需求。

Once a user decides to monitor the PDUs and RPPs in an application environment, the question about enabling connectivity depends on the implementation plan. Besides connecting power meters, circuit breakers, and current transformers that might use different protocols and interfaces than your EMS, ask the following questions.

Is the goal to retrofit existing PDUs or deploy a new one? Is there enough space for wiring design? How many PDUs will be connected to the network?

Answers to the above questions will reveal the need for a single-port or high port-density connectivity solution. For example, if you have limited space for retrofitting your existing PDUs in a relatively small-scale application, a single-port connectivity solution may be the ideal option due its compact design. In contrast, high port-density connectivity solutions can help save on costs if there is sufficient space to deploy multiple new PDUs.

Choosing an easy-to-use connectivity solution can save significant time and effort. In the installation stage, wiring can be painful when you are connecting dozens of PDUs to the same network. Check if the selected connectivity solution has features such as Ethernet cascading, which provides an efficient wiring solution across several PDUs and RPPs to the EMS located in the control center. When PDUs and RPPs are up and running, networking devices will still require backups and updates from time to time.

When unexpected network failures occur, meter data loss can lead to miscalculation of power consumption data, resulting in incorrect billing and incomplete power data for analytics. To enhance power monitoring system reliability, consider backup mechanisms from different angles. Start from the networking devices.

Dual-power inputs and high EMI immunity are features that can protect networking devices from electrical interference. Next, develop a redundancy mechanism for network transmissions. There are various network redundancy features in the market. When considering these options, see if their recovery times are acceptable for the needs of the power monitoring application.
