随着远海风电规模和容量的不断扩大，采用高压直流输电技术成为实现高效远距离输电的必然选择。其中，采用中频汇集经二极管整流单元DRU（diode rectifier unit）来实现高压直流输电的方案被认为是最优的方案之一。但是，DRU的非线性将使得风电并网变流器产生较重的谐波电流，对海上电网产生不利影响，威胁其安全稳定运行。为解决这一问题，提出1种远海风电中频汇集不控整流系统的谐波抑制策略。该策略通过采用瞬时功率理论在两相静止坐标系下实现对并网谐波电流的计算，结合模型预测控制MPC（model predictive control）主动调整风机并网侧电压波形，以有效减少由DRU产生的谐波电流，保障海上电网的安全稳定运行。仿真与实验结果验证了所提抑制策略的有效性与可行性。

Abstract

With the continuous expansion of the scale and capacity of offshore wind power, the adoption of high-voltage direct current transmission technology has become an inevitable choice for achieving efficient long-distance transmission, in which the use of medium-frequency AC collection with diode rectifier unit (DRU) to achieve high-voltage direct current transmission is considered one of the optimal schemes. However, the nonlinearity of DRU will cause wind power grid-connected converters to generate heavy harmonic currents, which will have adverse effects on the offshore power grid and threaten its safe and stable operation. To solve this problem, a harmonic suppression strategy is proposed for the medium-frequency AC collection and uncontrolled rectification system of offshore wind power. Under this strategy, the grid-connected harmonic current is calculated using the instantaneous power theory in a two-phase stationary coordinate system, and the voltage waveform on the grid side of the wind turbine is actively adjusted by combining with model predictive control (MPC). This can effectively reduce the harmonic current generated by the DRU and ensure the safe and stable operation of the offshore power grid. Simulation and experimental results validate the effectiveness and feasibility of the proposed suppression strategy.
