Problems solved by technology
[0012] The measuring point data in the DCS system cannot meet the data acquisition requirements of the multi-energy flow IEMS system SCADA
The measuring points collected by the existing DCS system only meet the actual production and operation needs of the power plant, and cannot meet the monitoring needs of the multi-energy flow system
The measurement point requirements proposed by the multi-energy flow system do not consider the actual operation of the power plant. Unreasonable and repeated measurement points will reduce the operating efficiency of the power plant unit and even bring some safety risks.

Embodiment Construction
[0020] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0021] Traditional energy services refer to providing customers with one-stop comprehensive services such as energy efficiency auditing, energy saving project design, raw material and equipment procurement, construction, training, operation and maintenance, energy saving monitoring, etc. Benefits come to profit and rolling development. However, with the continuous development of energy services in today's society, new integrated energy services oriented to customer needs must be the development direction of future energy services. New energy service refers to user-side demand-oriented, according to customer demand for energy utilization (electricity, industrial steam, heating, refrigeration, etc.), with the help of scientific and reasonable...

Description
technical field [0001] The invention relates to an arrangement structure of multi-energy flow measuring points for energy supply outside a distributed energy station. Background technique [0002] Background technology: The background technology related to this program includes two aspects: [0003] 1. Distributed Control System (DCS) [0004] Based on the microprocessor, DCS adopts the design principle of decentralized control function and centralized display operation, which has become the mainstream control system used in power plants. The operation station is used to display and record the process data from each control unit, and it is the operation interface for people to interact with the production process information. A typical operation station includes a host system, a display device, a keyboard input device, an information storage device, and a printout device, etc., and mainly realizes powerful display functions, alarm functions, and operation functions.
