| 摘要: |
| 随着新能源渗透率的不断提高，配电网主动调压成为维持系统稳定的重要手段。为研究当今负荷多样化配电台区的主动调压方法，首先研究了电机负载类型、负载率存在差异时的电压-功率调节特性，揭示了电机功率受带载情况影响的原因。提出了一种基于负载类型与负载率的台区电机分类方法，并建立了台区电机群分类聚合模型，能够有效降低模型复杂度。其次采用分类聚合模型研究了配电台区整体电压-功率调节特性，计及了静态、动态和电力电子等不同负荷类型及占比的多因素影响，并以实际农、商两典型行业为特例进行仿真分析。最后提出了配电台区主动调压方法。针对系统无功充足或无功不足两种情形以及台区主要负荷类型，调节电压使消耗有功或无功达到最小，实现系统经济运行。 |

| Abstract: |
| With the increasing penetration of renewable energy, active voltage regulation of a distribution network has become an important way to maintain system stability. To study the active voltage regulation method in a current power distribution station area with load diversification, first, the voltage-power regulation characteristics of the motor with different load types and load rates are studied, and the impact of the load conditions on motor power is revealed. This paper proposes a classification method of station area motors based on load type and load rate, and establishes a classification aggregation model of the motors, one which can effectively reduce the complexity of the model. Then, the overall voltage-power regulation characteristics of the distribution station area are studied using the classification aggregation model, considering different load types and proportions such as static, dynamic and power electronic load. Additionally, actual agricultural and commercial industries are analyzed as examples. Finally, the active voltage regulation method in the distribution station area is proposed. Considering situations of both sufficient or insufficient reactive power of the system and main load types in the station area, the voltage is adjusted to minimize the consumption of active or reactive power, realizing the economic operation of the system. |
