安科瑞IoT电能管理系统性解决方案在马来西亚某工厂的应用

时间：2021-12-16

1. 应用场景Application Scenario

对工厂的三相用电设备的用电量进行采集并上传至系统，从而使用户能够实现在PC上就能通过IoT EMS系统查看设备用电情况。

Customers need to collect the basic energy consumption data and upload it to management system so that they can realized real-time and remote data monitoring using their PC.

2. 技术选型 Technical Selection

2.1三相回路电压为415Vac L-L，额定电流不过80A AC，三相四线接线，电表方面选型三相带RS485（MODBUS-RTU）通讯的电表ADL400。

Rated voltage of 3-phase monitoring circuits is 415Vac L-L while the rated current is below 80A AC, thus selection of metering devices will be ADL400 3-phase energy meter with RS485 communication of MODBUS-RTU protocol

2.2工厂经确认后WiFi覆盖条件较好，频段为2.4GHz，方便提供220Vac供电，网关选用AWT100-WiFi搭配POW模块。支持广播自动抄表以便后续下行设备的添加。该网关上行为4GHz WiFi，采用MODBUS-RTU over TCP的透传通讯协议。下行为RS485通讯，采用MODBUS-RTU协议，从而与ADL400配合对数据进行上传至云服务器通向系统。

After discussing with the customer, factory is with stable 4GHz WiFi coverage and **,and a power supply of 220Vac is preferable. So, for the gateway parts, we select AWT100-WiFi which own auto-broadcasting function that can ease the later adjustment with subsequent ADL400. Also, AWT100-WiFi is paired with AWT100-POW power module.Other than that, since AWT100-WiFi is with upstream of 2.4GHz WiFi using MODBUS-RTU over TCP protocol and downstream of RS485 using MODBUS-RTU protocol to be paired with ADL400 for energy consumption data uploaded to cloud server and finally to the IoT System.

2.3测试阶段服务器使用我司已经租用的亚马逊云服务器以节省客户预算。

For pilot project phase, cloud server is highly recommended to use our company’s cloud server which has been rent on Amazon to save the customers’ budget on testing phase.

2.4根据需求系统选用IoT EMS系统，并提供3个月试用以便客户测试。

According to the request, IoT Energy Management System will be the most appropriate one and can provide 3-month free trial for testing use.

3. 初期方案架构Pilot Project Solution Structure

4. 后期方案方向 Plan after Pilot Project

若初期方案测试成功，后期方案方向为：

If pilot project proved to be successful, later plan should be as below:

4.1云托管方案：综合考虑云服务器租用成本以及点位数量不多的情况，云方案推荐为系统软件选用托管，云服务器依旧使用我司的云服务器。硬件设备层*改动，只需后续增订ADL400三相电能表，若点位数量需求较多，根据情况配套增订AWT100-WiFi网关。

Cloud Hosting Service Solution: Considering about the comprehensive cost of renting the cloud server and the amount of monitoring circuits, deployment of cloud IoT Energy Management System should be paired with hosting service. In this situation, customer don’t need to afford the rent of cloud server and will use our own cloud server. Also, for the hardware of this solution, no change need be done just like in the pilot project solution structure. Customer only need to order more ADL400 3-phase energy meter and maybe paired AWT100-WiFi gateway according to the number of subsequent request.

4.2本地买断方案：若客户对数据保密性比较有想法，后期推荐方向为IoT系统买断服务，服务器架设本地服务器并搭配工业交换机与UPS电源。硬件设备层电表依旧推荐ADL400，特殊型号ADF400L不推荐使用，原因是在三相四线接线为直通式接线而非互感器接入时，ADF400L的测量模块需求数量较多，无法减少成本。网关方面根据后期点位数量增配AWT100-CE或者APort100.

Local Buy-out Service Solution: If request from customers for data safety and Confidentiality is much more higher. The buy-out service of IoT Energy Management System to be paired with a Local Server will be the best choice. Yet the solution need to do a lot of change in hardware like. First, deploying of local server need to be paired with industrial switch and UPS. Second, for energy meter, ADL400 is still more recommendable.Since the special module, ADF400L Multi-circuit energy meter with built-in Ethernet communication won’t save much budget on the application of 3-phase wiring via direct connection instead of via CTs. At last, gateway need to be changed from AWT100-WiFi to AWT100-CE or Aport100 according to the amount of subsequent request.

摘要高压开关柜是电力传输系统的枢纽,起着通断、控制或保护等作用,**着系统安全运行。由于设备长期运行,高压开关柜的连接点因温度过高而酿成火灾的情况时有发生。这会造成经济损失甚至人员伤亡,因此,对高压开关柜内的设备进行温度检测变得尤为重要。本文根据高压开关柜的特点，对各发热节点进行实时温度监测和报警。0 概述某化工创建于1987年，公司产品制冷剂、绿色环保制冷剂、无水氟化氢、聚四氟乙烯、氟化盐及新
为什么要进行无功补偿？无功补偿的原理、形式是什么？
提及“无功补偿”，首先我们要了解无功功率的概念，什么是无功功率？人们对有功功率相对容易理解，因为它能做功、产生热量、带动电机旋转等。例如，当交流电通过纯电阻时，电流能使电阻发热，是实实在在能感受得到的功率。但“无功功率”一般则难于理解，它仅存在于交流电中，直流电不存在无功功率的问题。例如，当交流电流通过纯电容或纯电感负载时并不做功，也就是说纯电容或者纯电感负载不消耗有功功率，但在它们中流过的电流以
