There are 17 offices, 9 branch companies; seven heat source branch companies: First Power, Second Power, Dongshan Thermal Power, Chengnan, Chengxi, Xiaodian, Ruiguang, etc.

In 2011, Taiyuan Thermal Power Company further accelerated the construction of the central heating project, built a heating production management information center, and realized centralized monitoring and management of various heat source branches. Summarize the process operation data of each heat source branch company, supervise the operation status of each process in real time, realize the analysis of operation data, energy management analysis, achieve the goal of reducing energy consumption and saving costs, and improve the economic benefits of the enterprise; truly realize the central heating system The automation and informatization of the company have changed the situation in which branch offices are independent and decentralized.

2. Project features

1. Map display pipe network

The map shows the location of the heat exchange station, which can quickly locate the heat exchange station, obtain an overview of the heat supply information of the heat exchange station, and display key operating data with different color icons.

2. Redundant hot standby and bumpless switching

The hot-net monitoring server adopts the dual-system hot-backup method. When it is working normally, the hot-backup server synchronizes host data in real time. When the machine fails, the hot standby machine can replace the control function of the machine with the same process data as the machine, and realize a disturbance-free switching.

3. Topics on temperature analysis

Through the comparative analysis of the target heating temperature and the actual heating temperature of the same heat exchange station, as well as the comparative analysis of the heating temperature of different heat exchange stations, it provides a data information basis for the heating effect evaluation of the heating power station.

4. Special topic of energy consumption analysis

Through statistics, calculation, and comparative analysis of data, the energy consumption of the heating system is obtained, which provides an important basis for management decision-making.

Three, system architecture

Data collection summary layer

The data collection and collection layer adopts KingDataCollector and KingDataServer, which are professional data collection and collection software of Asia Control Technology.

Data analysis display layer

The database server is installed with the calculation and analysis software KingCaculation to perform data statistics. The equipment operating data and process data of each thermal station are loaded into the statistical unit for complex energy consumption analysis and calculation. Finally, the summary data analysis and display are carried out through the display platform KingGraphic, which is convenient Managers conduct cost calculations and evaluations based on the results of energy consumption data analysis.

Four, system function

1. Map information browsing

The analysis and display software KingGraphic of Asia Control Technology can embed map information, and quickly locate the heat exchange station through the distribution of geographic information maps of the entire heating network. You can get the heating information overview of the heat exchange station when you enter with the mouse, and the key operating data can be displayed with different color icons.

2. Online real-time monitoring

Obtain the operating process data of each heat exchange station in real time and display it in the process process screen. The dynamic and realistic process operation screen enables the staff to achieve the effect of being on the spot.

3. Topics on temperature analysis

Through the comparative analysis of the target heating temperature and the actual heating temperature of the same heat exchange station, as well as the comparative analysis of the heating temperature of different heat exchange stations, it provides a data information basis for the heating effect evaluation of the heating power station.

4. Energy consumption data analysis

Through statistical analysis, calculation analysis, and comparative analysis of the data, the energy consumption ratio of each process of the heating system is obtained, and the heat load and thermal efficiency of different heat exchange stations are obtained. The detailed information of cost consumption can be clearly obtained and provided The comparative analysis chart of various data provides an important basis for management decision-making.

5. Production report

Production reports mainly include real-time data reports, historical reports, and statistical analysis reports. The real-time data report displays the changes of production data in real time, and monitors the real-time operating parameters of the entire network in real time; the historical data report refers to query and display historical operating data according to the set conditions, and generate daily, monthly, and annual reports. The query time, query variables, etc. can be set, and different reports can be generated according to the query conditions. The report saving function can be realized, and it can be saved as a report in excel format; the statistical analysis report can realize data accumulation statistics, calculation statistics, etc., and can realize report printing and export Function.

6. Alarm function

The monitoring system has an alarm function. When a process alarm is generated, the client system pops up an alarm screen, accompanied by voice prompts. The alarm printer prints out the alarm information, the alarm window displays the alarm location, reason, time and other relevant information, and the operator confirms the process alarm. Maintenance engineers can define different priorities of different process alarms according to process requirements. The alarm history record can be queried by custom conditions. The alarm limit can be dynamically set online.

7. Annotation function

The monitoring system operator station is equipped with a comment function for all equipment, and the monitoring system is equipped with a special comment list to store the operating information of a given equipment.p>

8. Trend curve

The trend curve includes real-time running curve and historical trend playback curve. The real-time running trend curve shows the real-time running changes of various operating parameters; the historical trend playback curve is used to reproduce the historical operating conditions of the parameters. It can be set to display data at any time period to realize historical playback Features.

9. Access control

The monitoring system is equipped with an access control function. Through the access control function, the system gives the operator corresponding authority. Operator authority can be configured, and each operator's authority is unique. The monitoring system can be divided into different fields according to responsibilities, and the selected process display, alarm list and report form are only open to relevant operators.

Five, project summary

The system adopts advanced visualization solutions, and realizes the centralized monitoring and control of the operating parameters of the heating network and the heat exchange station through the feature-rich configuration software. The heat exchange station is unattended, and the centralized collection and Management greatly provides the stability and efficiency of the entire heating network system, saving huge manpower, material and financial resources. At the same time, the system has good scalability, leaving a data interface for future system upgrades and expansion.
