The power distribution room that Lao Wang was in charge of performed exceptionally well last year, with significant improvements in both safety and stability. At the beginning of this year, Lao Wang was officially promoted to Vice President of Energy Efficiency Operation Management, focusing on energy conservation and efficiency improvement.
" This year's target is to improve our energy efficiency by 20% . Whether we can achieve that depends on you. " No sooner had he been promoted than Old Wang faced his first challenge.
Back in his office, he pondered for a long time before dialing his friend Lao Zhang's number ...
Old Wang is under pressure to get promoted, and an old friend recommends Ming Shi's " Energy Efficiency +" product.
" Old Wang, long time no see! Welcome, welcome! " Old Zhang had been waiting for a long time.
“ Old Zhang, I’ve come here today specifically to learn from you! Your car companies have always been fast at energy efficiency management and digitalization, you have to tell me all about it today! Our steel mill needs to catch up. ” Old Wang said.
" No problem! It was mainly thanks to Schneider Electric's energy management system platform – Energy Efficiency Management + – that we were greatly helped. "
Old Zhang immediately launched into a long explanation: " First and foremost is the transformation of management methods: the energy efficiency management and system platform not only collects data on energy-consuming media such as water, electricity, and gas, but also integrates core energy efficiency-related data from production processes such as equipment, processes, workflow control, scheduling management, and personnel optimization. "
" Therefore, we can clearly see the energy efficiency operation of every process and every link in the whole plant on the same system platform, and find opportunities to optimize management processes and production processes and implement them, ultimately achieving the goal of overall energy efficiency optimization and improvement. " Old Zhang was very enthusiastic and kept talking.
" From the launch of the Energy Efficiency + platform in October 2017 to our first review in March 2019, the overall system energy efficiency improved by 20 % , and the energy consumption per vehicle decreased from 480 kWh / unit to 380 kWh / unit. Although automakers and steel mills focus on different indicators, their goal of reducing consumption and saving energy is the same. "
Overview of Enterprise Overall Energy Efficiency Data
“ I also invited an expert today, ” Old Zhang said, turning to another person beside him. “ This is S-Man , a service engineer from Schneider Electric. He led us in building the entire energy efficiency management and control system platform. Let him explain it to you in detail later. ”
Old Wang was surprised to meet S-Man here. "S-Man is an old friend of mine. They did our factory's MPS consulting services and switchgear adaptation and modification. "
" Since we're old friends, let's not waste any more time and look this way! "
Tailor-made solutions: Energy efficiency + intelligent computing requirements
As he spoke, Old Wang pointed to the 5x3 LED screen in the main control room , " This is the energy efficiency management and control system platform. The energy consumption of the entire factory and the operating status of every key piece of equipment are all displayed here. "
" In addition, we customized energy efficiency analysis functions such as energy cost overview, trend prediction, peak-valley-flat analysis, and shift analysis based on our factory's actual needs. "
“ Old Zhang is right , ” S-Man chimed in, “ Energy Efficiency Management + is a customized energy efficiency management platform based on the client’s industry characteristics and actual application scenarios. ”
" Both the overall system hierarchy, the range of data collected, and the display interface can be customized. "
" Furthermore, obtaining the data is only the first step. More importantly, it requires analysis. Our energy efficiency management and system platform customizes corresponding energy efficiency analysis modules and report dashboards based on the client's actual needs and the characteristics of their industry, providing clients with a basis for energy efficiency optimization and improvement measures. "

Cross-industry connectivity: Energy efficiency + Open door gathering of experts
" Some of the equipment and systems in our factory are not from Schneider Electric. Can they still be connected to the Energy Efficiency Management + system ? " Old Wang asked.
“ Of course, ” S-Man replied. “ Energy efficiency management + can achieve cross-brand, cross-device, and cross-system device data connectivity. ”
Second, the energy efficiency management system is compatible with all standard SCADA systems, including PSO power monitoring system and PME power management system .
Third, it can also integrate and customize system data, including MES , ERP , scheduling systems, etc. , according to the actual needs of customers .
For example, production scheduling and lighting control used to be two separate systems with no connection between them. However, through the energy efficiency management system, the data from the two systems can be integrated .
“ Yes, before, whenever we were on duty, we would turn on all the lights, regardless of whether there was production or anyone else in the workshop. Now, the lighting control system can optimize the management of the lighting system based on the actual shift schedule and output. When there is no one in the workshop or no production is taking place, the lights in the relevant areas will automatically turn off. This alone can save 780,000 yuan a year, ” Old Zhang said, sharing his experience.
Application of lighting control optimization
Flexible deployment: Choose between on-premises or cloud environments.
As they were talking, Old Zhang pulled out a tablet computer. " Moreover, this data isn't just available in the control room; it's also accessible on mobile devices, making it convenient to monitor the factory's situation anytime. "
" Is this being moved to the cloud? Our energy consumption data is very sensitive, it definitely can't be moved to the cloud! " Old Wang asked.
“ No problem, ” S-Man explained , “ The advantage of our Energy Efficiency + is its flexible deployment. We can choose between on-premises or cloud-based deployment based on enterprise needs, and we can even deploy at the group level. ”
" Like Lao Zhang, he opted for a group-level deployment. Now, a model energy-saving management center has been built across the entire group as a benchmark project, and the project has been replicated. Currently, at least six or seven similar projects have been successfully implemented within the group. "
" A superior energy management system is an effective tool to help companies achieve digitalization and improve their level of refined management. "
" With this system, the factory's energy efficiency optimization and refined management level can be significantly improved, " S-Man added.
postscript
Following Lao Wang's suggestion, the factory immediately implemented " Energy Efficiency Management +" , and within three months, it rectified and optimized the issues identified in the first round of energy efficiency data, achieving a comprehensive reduction in energy consumption both year-on-year and month-on-month that month. According to data forecasts, a 23% energy saving will be achieved by the end of the year, exceeding the energy saving target.
" It seems that achieving this year's goal is definitely not a problem, " Old Wang thought confidently.
Xiao Li from the equipment department suddenly called, " Engineer Wang, I have a question. How are the switchgear units we upgraded to Ecofit last year doing? The frequency converters on several of our blast furnace blowers are also nearing the end of their lifespan. We were planning to replace them, but the factory is cutting costs. Do you have any similar upgrade options for frequency converters? "
" If you're asking about this, then I can really tell you something about it ..."
