Steam metering management for thermal power plants, energy metering for self owned power plants, and standardization of pre charging systems for heating networks

Description :

Application of Qingdao STR/WEB/V2.0 Qingdao Zhiyuan Instrument Intelligent Heating System: Steam metering management in thermal power plantsThe main application is to achieve intelligence and ensure thermal balance of heat source output. Install temperature, pressure, flow and other sensors at each heat source unit and pipeline outlet to calculate the energy consumption of each link, display information on inlet and outlet temperature, pressure, flow and other aspects. The sensors will send the collected information to the heating dispatch center to achieve real-time monitoring of various parameter information.Steam metering management for thermal power plants, energy metering for self owned power plants, and standardization of pre charging systems for heating networksIn the application of heat source, it is also necessary to monitor load and weather changes, combine specific weather and load conditions, adhere to the principle of economic operation, compare the required heat with the heating amount, draw the trend curve of changes, and judge whether to start or stop the furnace. This will meet the heat needs of users without energy waste and save heating costs.

　　Qingdao Zhiyuan Instrument Prepaid Calculator complies with the JJG1003-2016 standard and meets the trade settlement requirements of the new metering regulations for integrated calculators.

　　A. Instrument model EF-II/TCP, LCD display screen.

　　B. The instrument has an accuracy of ± 0.2% and is capable of outputting 4-20mA analog signal current (output category can be freely defined).

　　C. The function of intelligent accumulation instrument is to measure pressure, temperature, instantaneous flow rate, cumulative flow rate, frequency, differential pressure, steam balance, power outage frequency, power outage and incoming call time, daily cumulative monthly cumulative query, etc. It is programmable and can set parameters according to actual needs;

　　D. Multiple cumulative methods (lower limit flow, over flow), cumulative coefficient (percentage) can be set. It can be set that when the flow rate is less than a certain percentage of the range (such as 10%), the lower limit flow rate will be accumulated according to this fixed value. It can also be set that when the flow rate is greater than a certain percentage of the range (such as 110%), the excess flow rate will be accumulated according to the set multiplier, thus solving the problem of low flow rate in small flow and excess flow measurement and meeting the actual needs of heat network calculation.

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdSteam metering management for thermal power plants, energy metering for self owned power plants, and standardization of pre charging systems for heating networksMeaning: In the context of vigorously building a smart city and promoting the development of "Internet plus" smart energy, the concept of smart heating came into being as an important branch of the energy industry. existingMeter reading on cloud platform of thermal power plantThere are still some issues during operation, such as insufficient remote points, relatively outdated control technology, high energy consumption, and low energy metering. Urban heating belongs to the main content of energy conservation and emission reduction. The development of contemporary heating systems must effectively combine traditional engineering with modern data science and technology, and improve the effectiveness of energy efficiency management by predicting the operation status of the heating network. The design of heating systems is often driven by demand, and predicting the demand for heat load on the consumer side plays a crucial role in improving the overall efficiency of the heating network operation.

Steam metering management in thermal power plantsOn site instrument installation:

Steam metering management for thermal power plants, energy metering for self owned power plants, and standardization of pre charging systems for heating networksInstalling a protective box on the primary measuring equipment of the pipeline can provide shelter from wind and rain, protect the equipment, and extend its service life; 2、 It can prevent unauthorized operation of measuring equipment. Any type of flow meter is not suitable for steam metering management in thermal power plants. Choosing a flow meter that is suitable for the operating conditions of thermal users is the rigorous method. For steam metering schemes, the mainstream schemes are divided into two types: vortex street type and differential pressure type. In the actual heating process, we will cooperate with your side to conduct on-site inspections to determine which flow meter is more suitable for use.
