In 2022, the national energy conservation with the theme of "green, low carbon, energy conservation first" is coming!
Today, the global energy shortage, climate change and environmental pollution are becoming increasingly prominent, and the international energy pattern is undergoing major and profound changes. The "fourteenth five year plan" and the long-term goal outline for 2035 clearly point out that achieving "carbon peak and carbon neutrality" is a necessary condition for China's economic transformation and upgrading, which puts forward higher demand for the energy field, and the innovation and transformation of the energy industry has entered the stage of accelerated development.
Thanks to the popularization of advanced technologies such as digital twin, cloud computing, Internet of things, 5g and AI identification, the digital transformation of energy system is the general trend. The key path for the transformation and upgrading of energy industry is to realize the optimization of system energy efficiency through digital means. How to realize the digitization and visualization of energy system status and efficient collaboration in subsequent operation management are the key points for the transformation and upgrading of energy industry, Digital twin technology is bringing new possibilities for energy management.

Low code visualization platform enabling
Cost reduction and efficiency increase, efficient delivery
In order to improve the living comfort of regional residents and reduce the regional carbon emission index, Zhejiang Yingji Power Technology Co., Ltd. and cecep urban energy conservation research institute have built a regional energy digital intelligence twin system in Changzhou high speed rail new city. By building a GIS based energy digital intelligence system, the mechanism model and data value are deeply mined to realize integrated dispatching command and independent data analysis, so as to realize the safe and efficient operation of the energy system, Achieve the purpose of energy conservation, emission reduction, quality improvement and efficiency increase.
The project relies on the background of centralized cooling and heating of Changzhou high-speed railway new town smart integrated energy station, located in the core area of Changzhou High-speed Railway New Town, plans to build 3, X energy stations, with an energy supply capacity of more than 6 million square meters, and the laying of energy supply pipe network of more than 35 kilometers. It provides centralized cooling and heating services for more than 20000 households and more than 1000 enterprises and institutions in the high-speed railway new town, which is the largest scale of centralized energy supply in the Yangtze River Delta, The regional clean energy supply project with the most sound government supervision mechanism.
The project mainly solves the common difficulties in regional energy management, such as:
1. The operation and maintenance of each energy subsystem is relatively independent, and there is an island of data / information, which is difficult to coordinate and optimize;
2. For the district central cooling and heating system, due to the large scale of the network side, complex topology and extensive operation management mode, there is a general energy waste of 10% ~ 20% in the operation process of the system;
3. In case of hidden system failure, the operation management personnel often shut down relevant equipment based on their own experience, without systematically considering the subsequent impact of this operation;
4. The existing operation mode is not enough to meet the lean production, transportation and consumption needs of the complex regional central cooling and heating system only based on the operation experience of the operation management personnel. It is urgent to conduct in-depth research on the key technologies of the efficient control of the regional central cooling and heating system to solve the technical difficulties of inaccurate load forecasting, low hydraulic imbalance and low success rate of hidden fault diagnosis.
For Yingji power, whose core business is the research and development of smart energy systems, the production of Yingji power's traditional large screen visualization project generally needs to go through the regular production cycle of "product design development reduction degree detection test online". Among them, a lot of effort is needed to run in the module of design and development reduction degree verification.
Therefore, a visual construction platform that can get started quickly, has rich components and supports custom development is the key to the efficient delivery of the project for Yingji power!
After a comprehensive comparison of multiple visualization platforms on the market, Yingji power has selected a partner capable of supporting its needs - yizhiwei easyv digital twin | Smart City Park factory water conservancy double carbon | 3D map data visualization screen
Yizhiwei easyv digital twin | Smart City Park factory water conservancy double carbon | 3D map data visualization large screen with simple, convenient, exquisite and easy to maintain advantages, reduces the time cost and labor cost of the overall project cycle reduction rework link. Designers can directly compare the effect drawings to complete the development and construction on easyv digital twin visualization platform, which saves the cost of design and development communication, It also saves more than 50% of the development cycle.
Through easyv, Yingji power has built a modeling and simulation platform for the regional energy pipe network of the new high-speed rail city. Based on the geographic information system, the whole process simulation model corresponding to the real energy system is established in the computer system. The simulation platform includes static simulation system and dynamic simulation system, which can calculate the distribution of temperature, pressure, flow, velocity and other parameters of the whole network, assist the planning and design of pipe network, and realize the soft measurement of the operation of the whole network.
