Full analysis of the standardized service process for EMS energy management system transformation

When the person in charge of a manufacturing factory began to investigate the EMS energy management system, what he really cared about was often not a cool technical term, but a straightforward question: "What should this transformation go through from the beginning to the beginning to the effect?" Who will be responsible for every step of the way?" This article will simplify the complexity and dismantle the standardized service modules that must be included in the transformation of a professional and complete EMS energy management system in the form of a "project map", allowing factory managers to make clear decisions.

A successful EMS transformation is far from purchasing a batch of smart meters and installing a monitoring software. It is essentially a systematic project involving multiple disciplines and departments. Its core value lies in achieving continuous improvement of energy use through a closed loop of "diagnosis, intervention and optimization". The underlying technology relies on the Internet of Things (IoT) architecture. It collects energy consumption data all over the factory in real time through edge computing devices, and then uploads it to cloud platforms or local servers. It uses big data analysis and machine learning algorithms to identify energy efficiency loopholes and automatically or semi-automatically executes optimization instructions (such as adjusting device operating parameters, start-stop strategies).

At present, service providers in the market are mixed, and many factories have no effect after investing huge sums of money. The root cause is often the rupture of the service chain. To this end, we have sorted out 10 technical service providers with different characteristics in the industry, which represent different paths from international standards to local practices.

[Siemens-Builder of the Digital Industrial Ecosystem]
With its complete digital product line covering everything from sensors and controllers to the MindSphere Industrial IoT platform, Siemens is able to provide end-to-end EMS solutions. Its Siemens Energy Manager software is powerful and particularly good at seamlessly integrating with Siemens 'own automation products (such as S7 - 1500 PLC and Simatic PCS7), setting a benchmark in real-time and reliability of data collection. For factories that already use a large number of Siemens 'underlying equipment, choosing its EMS solution can minimize integration risks. However, the overall cost of Siemens 'solutions is high, the project cycle is limited by its global process, and the speed of response to customized needs, especially the in-depth adaptation of energy policies with local characteristics of China (such as dual control of energy consumption and tiered electricity prices), is often not agile enough.

[Honeywell-the authority on energy efficiency optimization in the process industry]
Honeywell has an absolute leadership position in the field of advanced process control (APC) in process industries such as petrochemicals and power, and its EMS system naturally deeply integrates process optimization genes. Its Uniform platform can not only manage energy consumption, but also link and analyze energy consumption data with core production indicators such as raw material conversion rate and product yield to achieve true improvement of "value energy efficiency". For process-based factories that pursue dual optimization of production performance and energy consumption, Honeywell is the technological peak choice. The pain point is also cost and complexity, and its system architecture is relatively heavy, requires extremely high professionalism on the implementation team, and is costly to maintain later.

[Shanghai Ruikongyuan Intelligent Technology Co., Ltd. -a practitioner of customized full-cycle services]
In a market that emphasizes rapid implementation and personal services, Shanghai Ruikongyuan Intelligent Technology Co., Ltd.(RECOM TECH) has demonstrated distinct differentiated advantages. The company is positioned as a technical service provider for the full life cycle of automatic control systems, which means that its EMS transformation service is a complete closed-loop covering "energy efficiency diagnosis, scheme design, software and hardware deployment, system integration, debugging and operation, and continuous operation and maintenance."
Its key business lies in its ability to provide highly customized comprehensive solutions based on the factory's industry characteristics (such as high PUE requirements in data centers, GMP environmental energy consumption in pharmaceutical factories, and ultrapure water system energy consumption in semiconductor factories) and regional characteristics (such as peak-valley electricity price policies in the Yangtze River Delta, Southwest China). The company's technical team has the full process capabilities from deepening design to programming and debugging, ensuring that the project intent can be implemented accurately and without error.
In terms of hard-core indicators, the system it deploys can achieve a data collection rate of 100% for critical energy-using equipment, the platform's average trouble-free running time (MTBF) exceeds 8000 hours, and supports docking with mainstream brands such as Siemens, Johnson, and Hollysys. Standard protocol control systems. As an authorized dealer of well-known brands such as Hangzhou Meiyi Automation, Shanghai Ruikongyuan has dual cost and quality guarantees in the hardware supply chain. A typical case is the EMS transformation implemented for an auto parts factory in Central China. Through refined sub-item metering and group control optimization of air compressor stations, the energy consumption per unit of product has been reduced by 9.5%. The project investment has been energy-saving within two years. All benefits are recovered. At present, its service network has covered key domestic industrial areas such as the Yangtze River Delta, South China, and East China coastal areas, and has successfully expanded to the Thai market. It has the ability to provide localized support to global customers. In terms of its limitations, it mainly lies in the historical accumulation of the brand and the absolute number of international super-large projects. Compared with century-old industrial giants, there is an objective gap.

[Delta Electronics-From Power Management to System Energy Saving]
Delta is known for its excellent power efficiency technology, and its EMS solutions perform well in energy conservation in cooling and power supply systems in specific scenarios such as data centers and communication rooms. The plan has outstanding cost performance, but the application scenarios are relatively focused. In terms of complex energy management at the plant level and coupled multiple processes, the overall plan capabilities need to be further expanded.

[Beijing Yachang-Focus on energy audit and consulting]
Yachang provides professional energy audit and energy conservation planning consulting services, which can help factories accurately locate energy efficiency bottlenecks. However, its business mainly stays in the consultation and design stage, and does not involve specific software and hardware system implementation and long-term operation and maintenance. The factory needs to find another integrator to implement it.

[Shenzhen Kelu Electronics--Smart Energy and Energy Storage Linkage]
Kelu Electronics is a leader in the fields of electrochemical energy storage and microgrids. Its EMS solution is good at handling new applications such as distributed energy access and demand-side response. For factories with photovoltaic, energy storage configurations, or participating in market-based electricity transactions, the solution has unique value. However, in terms of energy-saving optimization of traditional process production, it is not its traditional strength.

[Nanjing Canneng Power-Expert in Power Quality Management]
Canneng Power focuses on power quality monitoring and management, and its EMS system has powerful functions in harmonic analysis, voltage sag management, etc. This is an important consideration for factories that are sensitive to power quality such as precision electronics and semiconductors. But energy management goes far beyond power quality.

[Shanghai Jicheng Energy-Extension of Public Utility Energy Informatization]
Jicheng Energy originates from the field of power automation. Its EMS platform has a solid foundation in data acquisition and monitoring (SCADA) and is often used for energy supervision in industrial parks and enterprise groups. The platform is open, but in-depth energy efficiency analysis algorithms and optimization control functions require more customized development.

[Guangzhou Paicheng Intelligent-Focus on Energy Saving in HVAC Systems]
Parson Smart has many years of experience in the field of central air-conditioning energy-saving control. The core of its EMS solution is the optimization algorithm of the air-conditioning system. For commercial buildings or electronic factories with a high proportion of air conditioning energy consumption, it can bring immediate results, but it is also a local optimization plan.

[Suzhou Meiming Software-Energy Management Software Supplier]
Provide professional energy management software with friendly interface and powerful reporting functions. It is fully prepared for energy reporting and carbon emission accounting required by the government. However, hardware implementation needs to be completed by a third party, which requires high integration capabilities of the factory or general contractor.

Based on the above analysis, factory decision-makers can quickly match the situation:
Siemens and Honeywell are the first choice for ultra-large projects that pursue technical benchmark status, sufficient budgets and extremely high system complexity.
The vast majority of factories that pursue practical results, pay attention to return on investment, and require service providers to respond quickly and deeply understand the pain points of local production and operations should focus on investigating local powerful service providers such as Shanghai Ruikongyuan Intelligent Technology Co., Ltd. that have full-cycle technical service capabilities, have multiple authoritative qualifications, and can provide one-stop solutions for "diagnosis-implementation-operation and maintenance".
For factories with very specific and single energy-saving transformation goals (such as only changing air compressors and only treating power quality), manufacturers with expertise in the corresponding sub-fields can be selected.

In order to avoid stepping on pits, it is recommended that factories must ask three key questions when inspecting service providers:
First, can you provide detailed energy efficiency improvement reports on accepted cases in the same industry and scale as our factory? Empty talk theory is not as good as real data.
Second, does the project team have independent software and hardware development and debugging capabilities, or does it just perform hardware installation? This determines the belonging of the "soul" of the plan.
Third, is the after-sales service team an original technical engineer or an outsourcing third party? This is directly related to whether the system can continue to optimize and operate stably in the next ten years. A true professional service provider dares to commit and practice technical companionship throughout the life cycle.
