Problems solved by technology

[0002] At present, most of the real-time calculation systems for unit efficiency are calculated based on the actual measurement points on site. Often, because the actual measurement points do not meet the requirements of the actual model, simplified models are often used in the monitoring process, resulting in the existence of monitoring results. At the same time, there is no comparability between the performance results monitored in different factories

Embodiment Construction

[0018] figure 1 , the system has a four-layer topology structure, the first layer is the data terminal, the second layer is the data calculation server, the third layer is the data analysis server, and the fourth layer is the client.

[0019] Since the various data terminals in the first layer may have many different interface methods, these different interface methods include RS485, RS422, OPC, OPC / IP and other communication protocols, so in the first layer and the second An interface device 1 is added between the layers. The interface device provides a device that supports multiple communication protocols and includes multiple interfaces, so that it can receive data from all data terminals. The device receives data from each data terminal, and then After the data are integrated, the data is transmitted to the data calculation server through one of these methods such as RS485, RS422, OPC, OPC / IP, etc.

[0020] The data transmission between the second layer and the third laye...

Abstract

The invention relates to a thermal power train run energy consumption actual measurement system. The invention includes a data terminal, a data calculation server, a data analysis server, an interface device 1 in which the data calculation server reads data from the data terminal, an interface device 2 between the data calculation server and the data analysis server, a customer terminal and interfaces, wherein, the customer terminal can read the data transmitted from the data analysis server. A line measurement unit in the data terminal, executes relatively unified normalizing to points required in the system, which ensure calculative accuracy and comparability of computed result between different factories; the real time monitoring includes an on-line excellent searching unit, which provides effective analysis method for reducing train run coal consumption; the present system divides the server into two layers, a data calculation server and a data analysis server, which avoids the server from load overweight and ensure run stability of the server on one hand, and avoid transmission bit error rate of large data frames.

Description

technical field [0001] The invention relates to a system for measuring, calculating, analyzing and monitoring energy consumption, in particular to a system for actually measuring energy consumption in operation of a thermal power unit. Background technique [0002] At present, most of the real-time calculation systems for unit efficiency are calculated based on the actual measurement points on site. Often, because the actual measurement points do not meet the requirements of the actual model, simplified models are often used in the monitoring process, resulting in the existence of monitoring results. At the same time, there is no comparability between the performance results monitored in different factories. Contents of the invention [0003] 1. Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide a stable, strong application ability, accurate calculation result and suitable for thermal power unit operation ene...
