The flexible on-load voltage regulator has two performances, generating reactive power and performing continuous voltage regulation. Based on the above two factors and the proposed strategies, two situations of large load access and small load access are designed.
Abstract: The traditional on-load voltage regulating transformer uses a mechanical switch or an anti-parallel thyristor as a tap switch. By changing the tap position and adjusting the voltage according to a certain discrete step, the reactive power shortage can only be solved by an additional reactive power compensation device.
At present, the voltage regulation strategy of the power system is based primarily on the coordinated control of capacitors, STATCOM and OLTC. On the one hand, it is possible to use methods such as decentralized control , multi-mode optimization and multi-agent control to adjust voltage.
The grid side voltage is 120 kV, and the on-load voltage regulation device has a transformation ratio of 120 kV/25 kV and a capacity of 47 MVA. Set the reference voltage as V r e f = 1 (pu). At 20 s, the loads of 18 MW/5 Mvar and 1 MW/1 Mvar are connected to Bus2 to simulate different degrees of voltage fluctuations.
The stepless voltage regulation can quickly and accurately reach the set reference voltage value, and can release the reactive power capacity of the STATCOM in a very short time to ensure that it has sufficient reactive power regulation performance.
When using the traditional OLTC for voltage regulation, the taps are mostly controlled by mechanical devices, and the adjustment process needs to move the tap position many times, which increases the loss of the equipment and the adjustment speed is slow.
