Description: 对广大供电企业来说，用户功率因数的高低，直接关系到电力网中的功率损耗和电能损耗，关系到供电线路的电压损失和电压波动，而且关系到节约电能和整个供电区域的供电质量，这是众所周知的道理。提高电力系统的功率因数，已成为电力工业中一个重要课题。文中简要集中探讨了影响电网功率因数的主要因素以及低压无功补偿的几种实用方法，和确定无功补偿容量从而提高电力系统功率因数的一般方法。-For the majority of power supply enterprises, the level of user power factor, is directly related to the power loss and power loss in the power grid, related to the voltage of the power supply line losses and voltage fluctuations, but also to save energy and supply area for electric quality, this is a well-known truth. Improve the power factor of the power system, the power industry has become an important topic. Briefly several practical approach focuses on the main factors affecting the grid power factor and low voltage reactive compensation, and determine the reactive power compensation capacity of the general method to improve the power factor of power system.

Description: a new circuit topology of a
phase-locked loop that can be used for synchronising a singlephase
wind turbine generator (WTG) with the low voltage utility
grid. The circuit is based on the time-delay digital tanlock loop
(TDTL) architecture and was modelled and simulated using
Simulink/MATLAB. The results presented demonstrate the
ability of the circuit not only to synchronise a WTG with the grid,
but also to re-gain synchronization following a sudden
disturbance in the grid voltage. The simulated disturbances
included a ramp and a multi-step change in the phase of the grid
voltage waveform. Platform: |

Description: In this paper, a simple single-phase grid connected photovoltaic (PV) inverter topology consisting of a boost section, a low-voltage single-phase inverter with an inductive filter, and a step-up transformer interfacing the grid is considered. Ideally, this topology will not inject any lower order harmonics into the grid due to high-frequency pulse width modulation operation. However, the nonideal factors in the system such as core saturation-induced distorted
magnetizing current of the transformer and the dead time of the inverter, etc., contribute to a significant amount of lower order harmonics in the grid current. A novel design of inverter current control that mitigates lower order harmonics is presented in this paper. Platform: |
