Sfere-PMS power monitoring system

The Ngari area is the "Secret Realm of Tibet" in the eyes of many people, but the average altitude above 4500 meters is prohibitive. Ali Kunsha Airport is located in Kunsha Township in the Gor Zangbo (Shiquan River) River Valley with an altitude of 4274 meters. It is a 4D-level Chinese Plateau Airport. On July 1, 2010, li Kunsha Airport was officially opened to traffic, with a 4500 meter runway, which built the "Golden Bridge in the sky" for communication between Ali and the world.

This year is the 10th year of navigation. This "Golden Bridge in the Sky" has opened a "Road to Happiness." The navigation has brought a line of social progress, transportation guarantee line, air lifeline, and national unity line to Ali, which has played a key role in promoting Ali`s economic development and helping to fight poverty.

Sfere-PMS power monitoring system

The Power Monitoring System adopts a hierarchical and distributed structure, which is divided by interval units and designed in modularization. It is consisted of system management layer, network communication layer and field measurement and control layer.

1 System management layer

It is composed of system software, industrial computer, UPS power supply, printer and other hardware to realize the monitoring, analysis and management functions of the whole system.

2 Network communication layer

The network is composed of various communication equipment and communication media to realize the information exchange between the system management layer and the on-site measurement and control layer equipment.

3 Field measurement and control layer

It is composed of various intelligent instruments and devices installed on site to realize the functions of measurement, monitoring, communication and control.

System functions

System operation monitoring

It supports the primary diagram display mode of power transformation and distribution system, real-time acquisition and display of current, voltage, power, power factor and other electrical parameters of high and low voltage circuit. It has various display colors to distinguish the opening and closing state display and provide sound and light warning prompts.

Remote control and parameter configuration

It can realize remote opening and closing control of designated circuits, protection on / off setting, alarm protection parameter adjustment for the specified circuit, and conduct event analysis and fault recording data analysis for alarm or trip circuit, find out the cause of alarm or trip, provide various alarm fault display for operators, prompt potential fault report of the system, and provide effective guarantee for safe operation of the system.

Trend curve analysis

The trend curve system can continuously monitor the operating parameters of the equipment in real time, such as the power load, waveform capture at the moment of fault occurrence, help users dynamically analyze the historical changes of various data, and provide powerful data basis for managers to predict the parameter changes and future trend of power supply system in a certain period of time.
