在中、低压配电网系统中出现了大量不平衡负荷,以及一些单相大容量的负荷(例如电阻炉、供应感应炉、石墨化炉之类),这些使得电网三相电压不平衡日益严重,严重威胁电力系统中的安全和经济运行。根据三相不平衡补偿原理,获得电纳的给定值,达到补偿效果。最后给出在MATLAB下做出的仿真,仿真结果表明可以实现对三相不平衡负荷的无功功率补偿。
In the medium and low voltage distribution network system, a large number of unbalanced loads, as well as some single-phase high-capacity load (such as resistance furnace, induction furnace, graphitization furnace and the like), which makes the grid three-phase voltage imbalances increasingly serious , A serious threat to the safety and economic operation of the power system. According to the three-phase unbalance compensation principle, the given value of the susceptance is obtained, and the compensation effect is achieved. At last, the simulation made under MATLAB is given. The simulation results show that reactive power compensation can be achieved for three-phase unbalanced loads.
