System Overview:-------------------------------------------------------------------------------------------------------

The Yongnuo YN-5000 power monitoring system utilizes computers, metering protection devices, and bus technology to centrally manage real-time data, switch status, and remote control of medium and low voltage distribution systems. This power monitoring system can provide enterprises with an integrated monitoring solution.

This system is independently developed by resource developers who have been engaged in power software design for many years in logging. It uses WINDOW2000/NT/XP as the operating platform and large-scale relational databases such as OracleSQL Serve2000 as the database platform. The data is secure and accurate, and the system has an automatic backup function, so there is no need to organize the data; Rich configuration software packages can accurately and real-time describe the on-site situation through network and real-time libraries.

System Overview:-------------------------------------------------------------------------------------------------------

The Yongnuo YN-5000 power monitoring system is based on the Client/Server mechanism, follows international standards, and meets the design requirements of an open system, achieving openness from the system platform layer to the application layer; Provides good interoperability and distribution, facilitating the sustainable expansion of user level functions, enabling it to adapt to the constantly changing business needs of automated data center monitoring systems; By adopting flexible software and hardware configuration schemes, various scales and requirements of skip reading, distribution scheduling or integrated management systems can be constructed.

The Yongnuo YN-5000 power monitoring system is designed following a three-layer architecture, which is divided into a data system layer, an application service layer, and a customer application layer. The various modules in the three-layer structure work together. The database system layer is responsible for storing system parameters, data, and historical record data, while also completing classification statistics and organizing historical data. The C/S system structure of the system sampling standard, where the client is only responsible for requesting application tasks. The request information is sent to the designated application server through the system's network subsystem, and the application server completes its respective logical functions of concern. The advantage of adopting this approach is that the client only cares about the customized tasks and interface display results, and the specific business logic is completed by the application server, thus ensuring the modularity of development and the maintainability of the system.

Adopting a unified access interface to achieve standardization of access. All client application layer functions, application servers, and database system modules adopt standardized and unified development methods and access interfaces. The client application server and database system modules adopt standardized and unified development methods and access interfaces. The deployment of client application layer functional modules and application server functions does not depend on host nodes, and can be freely configured according to user requirements. They can run on one host system or be distributed and deployed according to their functions.

TCP/IP network protocol is currently the most popular and stable network protocol. The system has developed a dedicated communication layer on top of the TCP/IP network protocol, reducing the utilization of system resources.

The Yongnuo power monitoring system software provides a basic platform for real-time data acquisition, switch status detection, and remote control of the system with the help of computers, communication equipment, and metering protection devices. The network structure of the system consists of three parts: management layer (station control layer), communication layer (middle layer), and interval layer (on-site monitoring layer).

Monitoring configuration software functions:-------------------------------------------------------------------------------------------------------

User Management

This software can grant different permissions to users of different levels, ensuring the security and reliability of the system during operation. For the closing/opening operation of a certain important circuit, the operator level user needs to input the operation port. In addition, the engineer level user needs to input the confirmation password to complete the operation.

The interface of the table module is shown in the figure:

data acquisition and processing

This monitoring system can collect real-time and timed data of various electrical parameters and switch status of on-site equipment (including three voltage, current, power, power factor, frequency, point method, temperature, switch position, equipment operating status, etc.), and display the collected data directly or generate new intuitive data information through statistical calculation for display (total system power, maximum load value, upper and lower limits of power factor, etc.), and store important information in the database.

The interface of this module is shown in the figure:

Report Manager

The system has a standard energy report format and can design a report format for the load of tree demons according to user needs. The system can automatically calculate. It can automatically generate various types of real-time operation reports, duration reports, event fault and alarm record reports, operation record reports, etc. It can query and print system records and all data values, and automatically generate daily, monthly, and annual reports of electricity.

The interface of this module is shown in the figure:

Trend curve analysis

The system provides real-time curve analysis, historical trend curve analysis, and daily, monthly, and annual bar chart analysis; Analyze the current load operation status of the circuit by calling the real-time curve interface of the relevant circuit. The historical trend of the system refers to the ability of the system to view the historical trend of all stored data, which facilitates quality analysis of the monitored distribution network by engineering personnel.

Real time electrical parameters

The system provides real-time display of electrical parameters, which can display the electrical parameters of different electrical devices in real time according to user needs, and can print and output relevant data.

The interface of this module is shown in the figure:

Time recording and fault alarm

The system has a trusted recording function for all user operations, switch changes, parameter limit violations, and other actual user needs, including the time and location of the time occurrence, whether the current duty personnel have confirmed the time, etc. It also has an audible alarm function for switch changes, parameter limit violations, and other information. At the same time, it automatically sends control instructions or prompts the duty personnel to quickly troubleshoot the equipment.

The power monitoring system should choose power monitoring instruments:-----------------------------------------------------------------------------------------------

Power monitoring instruments are designed for power systems and industrial and mining enterprises. Designed for the power monitoring needs of public facilities and intelligent large public buildings. It can measure all commonly used electrical parameters with high precision, such as three-phase voltage, three-phase current, active power, reactive power, frequency, power factor, four quadrant electrical energy, etc. It uses a highly visible LCD to display instrument measurement parameters and operational information of the power grid system. There are many functions and models of power monitoring instruments, and their prices are also different. Therefore, they should be selected reasonably to achieve the best cost-effectiveness.

Configuring power monitoring instruments in the power monitoring system has significant advantages such as simple implementation and low investment. It can conveniently and real-time monitor the operation status of the distribution system, unify the management of on-site electrical equipment, and eliminate the tedious work of staff recording on site. The system manages and analyzes the historical operation data and status of various electrical equipment, making it easy for maintenance personnel to clarify the equipment status, formulate detailed equipment maintenance plans, reduce staff, and improve efficiency.
