Project Background
Liunan Second Expressway is also known as Liuzhou Jingheshan to Nanning Expressway. The main line of this project starts from the vicinity of Luoman Town, Liuzhou City, connects Liuzhou Expressway by Sanjiang, and finally arrives at Wutang Town, Nanning City, and Liuzhou South Expressway. The highway is one of the highways with the largest traffic volume in Guangxi in recent years. The second expressway in Liunan City has a total length of about 199 kilometers and a design speed of 120 kilometers per hour. It adopts the two-way four-lane standard and builds 8 connecting lines at the same time. The total investment is estimated to be 20.749 billion yuan. There are 13 bridges, 4 service areas, 3 After the project opens to traffic, the driving time from Shanglin to Nanning will be shortened to 1 hour, effectively relieving the traffic pressure on the original Liunan Expressway, especially from Liujing to San'an.
Applications
This project uses our company's reactive power compensation series products, including static var generators, intelligent combined anti-harmonic compensation devices, etc. Mainly used for reactive power compensation. Effectively improve the power factor, reduce losses, and ensure stable and reliable operation of power equipment.
Advantages of static var generator products
1. Capacitive inductive load -1~1 compensation.
2. Three-phase unbalance compensation.
3. The working switching frequency is 10K, and the dynamic compensation is extremely fast response.
The HYSVG static var generator detects the load current in real time through the external current transformer (CT), analyzes the reactive power content of the load current through the internal DSP calculation, and then controls the PWM signal generator to send a control signal to the internal IGBT according to the set value. Make the inverter generate reactive power compensation current that meets the requirements, and finally realize the purpose of dynamic reactive power compensation.
HY series intelligent combined anti-harmonic low-voltage power capacitor compensation device is a new generation of reactive power compensation equipment used in 0.4KV low-voltage distribution network for high efficiency, energy saving, harmonic suppression and power factor improvement. It replaces the traditional control by intelligent reactive power compensation. It is a reactive power compensation equipment composed of parts such as circuit breakers, fuses, switching switches, filter reactors and power capacitors.
Anti-harmonic smart power capacitors are designed for the case that the harmonic content of the power network is high and the conventional smart capacitors cannot operate normally. impact and improve the quality of electricity consumption.
