Application of Kingview software in the monitoring system of Laos nameng substation

I. background information

Laos nameng substation monitoring (Laos Nanmeng hydropower control and has also made stricter regulations for employees in pole changing, aluminum output and other operation links. The monitoring system of water conservancy substation commissioned by Beijing Yakong science and technology to develop for Acheng relay, including software development, drive development Engineering configuration work, the development of this system can not only create high economic benefits for customers, but also a successful case of Beijing Yakong technology products in developing the Southeast Asian market

II. Project overview

the microcomputer integrated automation system is used for the monitoring of namang substation in Laos. Comprehensively consider the functions of substation data acquisition, control, protection, measurement, signal, etc

the system adopts a layered and fully open structure. The system is divided into two layers: substation layer and bay layer. The configuration of monitoring system is shown in figure -1. Among them, the substation layer is composed of two hot standby 1 #, 2 # operator master stations, one training simulation master station, GPS satellite clock positioning system and printer. The composition of the Bay layer is: 8 industrial control computers (8 industrial control computers are respectively connected and communicated with protection, monitoring, analog screen drive, watt hour meter and other equipment), microcomputer five prevention locking device, DC power supply, etc. 1 #, 2 # operator workstation, training simulation master station, GPS satellite clock positioning system, network printer, 8 industrial control computers, microcomputer five prevention locking device, DC power supply and other equipment are connected to Ethernet through German Hessman mice3000 series switch

the composition and functions of substation floor and bay floor are introduced below

1 substation level

1.1 1 #, 2 # operator master station

1 #, 2 # operator master station are hot standby for each other, and their main functions are to complete substation control, protection, measurement, signal, etc

1.2 when the simulation training master station is offline, it is used to simulate the actual operation of the substation and train operators for various operations and maintenance. The simulation training master station can simulate various operation conditions of the substation, collect actual parameters and simulate operation, but it does not export. It can simulate the actual operation of the power station and train operators without causing maloperation

1.3 GPS satellite clock positioning system

gps satellite clock positioning system uses tcp/ip protocol to time computers and automatic equipment in the network through the network port

2 compartment tear resistance

2.1 # industrial control computer and its connecting equipment

# industrial control computer communicates with the protection and monitoring equipment of four 115kv lines (thanaleng, naxaythong, nammang-3 Line1, nammang-3 line2) respectively, collects data, uploads it to the substation layer, and then transmits the instructions of the substation to control the control and protection equipment connected with it

2.2 # industrial control computer and its connecting equipment

# industrial control computer communicates with the protection, monitoring and tap equipment of two main transformers (1 # main transformer T1 and 2 # main transformer T2) respectively, collects data, uploads it to the substation level, and then transmits the instructions of the substation down to control the control and protection equipment connected with the double action system

2.3 7# industrial control computer and its connecting equipment

4 capacitor banks (capacitor bank1, capacitor bank2, capacitor bank3, capacitor bank4) protection and monitoring devices, 6 22kv feeders (feeder.1, feeder.2, feeder.3, feeder.4, feeder.5, feeder.6) protection and monitoring devices, station transformer protection and monitoring devices, 22kv bus coupler protection and monitoring devices, power supply standby switching devices, and 7# industrial control computer.Communications. The industrial computer collects data, uploads it to the substation layer, and then transmits the instructions of the substation to control the control and protection equipment connected with it

2.3.1 measurement and control function of capacitor bank

(1) measure three-phase current and reactive power between capacitors

(2) circuit breaker position monitoring, tripping control, circuit breaker spring energy storage status monitoring

(3) there is a locking circuit to prevent inadvertent switching into the capacitor device when the protection trips, and a locking release control switch is set

(4) receive the command from the station level computer and switch the capacitor bank

2.3.2 22kv feeder measurement and control function

(1) measure the three-phase current, active power, reactive power and power factor of the feeder

(2) circuit breaker position monitoring, tripping control, circuit breaker spring energy storage status monitoring

2.3.3 station transformer measurement and control function

(1) measure the three-phase current at the low-voltage side of the transformer

(2) circuit breaker position monitoring, tripping control, circuit breaker spring energy storage status monitoring

2.3.4 22kv bus coupler measurement and control function

(1) measure three-phase current of bus coupler, voltage and frequency of two sections of bus

(2) bus coupler position monitoring, tripping control, bus coupler spring energy storage status monitoring

2.4 8 # industrial control computer and its connecting equipment

8 # industrial control computer communicates with 115kv bus measurement and control device, watt hour meter, analog screen drive, collects data, uploads it to the substation layer, and then refers to 3 of the substation The Rockwell hardness (HR) order is transmitted downward to control the control and protection equipment connected with it

2.4.1 115kv bus measurement and control function

(1) measure the three-phase voltage, line voltage and frequency of the bus

(2) monitor the position of side bus circuit breaker, disconnector and grounding switch, monitor the energy storage state of circuit breaker spring, and have the function of event sequence recording; Breaker and disconnector tripping and closing control

2.4.2 driving function of simulation screen

the simulation screen is driven by the computer and is used for the simulation display and electrical measurement display of the main wiring of the substation

2.4.3 function of watt hour meter

watt hour meter is used to collect the electricity measurement of substation, which is collected by 8 \industrial computer and uploaded to the substation layer

2.5 microcomputer five prevention locking device

(1) microcomputer five prevention locking is directly connected to the Ethernet, and the required switch signal position comes from the processed signal of the substation layer, and exchanges information with the substation layer

2.6 DC power supply device

is used to collect various parameters of DC power supply

the main reason why customers choose Kingview is its powerful function, strong scalability of external connected equipment and reliable operation

III. The main functions of the project are as follows:

the project uses almost all the functions of Kingview. The project has the characteristics of real-time, accuracy, stability and reliability, and the software runs stably and reliably. Based on the original functions of Kingview, customized development has been carried out from the following aspects:

1 switch remote control function

remote control function has the function of back calibration and delay, which is processed in the corresponding drive and configuration to meet the functional requirements

2 modification of the fixed value of power equipment

the number and difficulty of the modified fixed value variables use the current configuration
