Ecava IGX Takes Care of Power Distribution for MHB

Ecava IGX负责MHB的电力分配

How It Started

Malaysia Marine and Heavy Engineering Holdings Berhad (MHB), or formerly known as MMHE, is a leading offshore and marine services provider in Malaysia, focused primarily on the oil and gas sector. Operations across the MHB yards located in Pasir Gudang (Johor, Malaysia) are supported and supplied by the power distribution. These extremely high voltage powers are monitored and controlled by the professional team in a power facility room located in the administration building of MHB. There are rows and rows of panels comprising with numbers of power meters in the control room area, in which the operators are required to walk to each of them in order to monitor the entire power distribution. Imagine if there is an emergency situation, it is very important for the operator to be notified at the earliest moment to control any unwanted loss, but it could be difficult to achieve by their manual monitoring work routine. Therefore, MHB has chosen Ecava IGX SCADA to build an accurate and automated monitoring system to guard the power plant operation.

马来西亚船舶和重型工程控股公司Berhad(MHB)是马来西亚领先的离岸和海上服务供应商，主要专注于石油和天然气行业。MHB跨区域运营位于Pasir Gudang(马来西亚Johor)的船厂由配电系统支持和供应。这些极高的电压功率由专业团队在位于MHB行政大楼的电力设施室中进行监测和控制。控制室区域内有一排排带有电能表数目的面板，其中要求操作者步行到每一组，以监测整个电力分配情况。试想一下，如果出现紧急情况，尽早通知经营者以控制不必要的损失是非常重要的，但他们的人工监测工作很难做到。因此，MHB选择了Ecava IGX SCADA来建立一个准确、自动化的监控系统，以保障电厂的运行。

Operator had to monitor each panel manually everytime during the job routine schedule. Power Distribution Network by Ecava IGX provided the solution to monitor the system in the efficient way.

在日常作业计划中，操作员每次都要手动监控每个面板。Ecava IGX公司的配电网络为系统的高效监控提供了解决方案。

Power Distribution Network (PDN) System by Ecava IGX

基于ECARA IGX的配电网(PDN)系统

In this project, Ecava IGX is required to monitor the power meter readings accurately. The Power Distribution Network (PDN) system is designed to achieve this by having the best connection architecture in order to yield the efficiency. All the digital power meters will be transmitting serial data via Modbus RTU protocol to MOXA MGate serial converter. These serial data will be converted to digital data by MOXA MGate, then send to Ecava IGX SCADA server via Modbus TCP/IP protocol. PDN system will process these data to present them on mimic screens to ease operators’ routine work, as well as record them as real-time / historical trends and reports.

在这个项目中，Ecava IGX需要对电能表的读数进行准确的监测。电力分配网络(PDN)系统就是为了达到这一目的而设计的，它采用了最佳的连接结构，从而提高了系统的效率。所有的数字电能表都将通过Modbus RTU协议传输串行数据到MOXA MGate串行转换器。这些串行数据将通过MOXA MGate转换成数字数据，然后通过Modbus TCP/IP协议发送到Ecava IGX SCADA服务器。PDN系统将处理这些数据，将其显示在模拟屏幕上，以方便操作者的日常工作，并将其记录为实时/历史趋势和报告。

PLC (Programmable Logic Controllers) is equipped in this project to aid the control operation of switchgear for PDN. SCADA mimics are designed imitate the hard button switchgear panel in an identical way, the reason is to target operators’ convenience in familiarize with the automated PDN system. Operators can initiate requests on the panel mimic screen easily to control the switchgear operation.

本项目采用可编程控制器(PLC)辅助PDN开关柜的控制操作。SCADA模拟系统是以相同的方式模拟硬按钮开关面板柜，目的是为了方便操作人员熟悉自动化PDN系统。操作人员可以在面板模拟屏幕上简单地发起请求，以控制开关柜的操作。

PDN系统的SCADA仿真是为了模拟开关柜而设计的。

Other than that, since there are different voltages across the entire power distribution, different color codes are used to design the mimics. The approach shall lead to easier inspection whenever it is required.

除此之外，由于整个功率分布都有不同的电压，所以使用不同的色码来设计模拟电路。这种方法应在需要时使检查更容易。
