“…There have two main types of output filter for inverters in grid-connected mode, i.e., L-type and LCLtype filter. Besides, the LC-type filter is mainly used in the islanded mode [70]. The equivalent output impedance of each inverter will easily be changed due to the deviation of filter parameters.…”

“…In some way, this solution can be simplified, if a single gas generating device connects to a substation with fixed topological structure by a limited number of automatic switches (Wai et al 2013). The status signals can be directly sent to the gas generating devices from each monitoring point, without the central control unit.…”

KEYWORD: power grid; strategy of gas power station; communication; synchronous generator; grid connected inverter ABSTRACT: The Chinese economy is developing rapidly, the demand for energy is getting more and more intense. With the development of coal mine, the utilization of gas is getting more and more important, and the numerous gas generating units will be connected to the power grid. Due to the characteristics that the unit capacity of gas generator is small, the gas safety requirements is high, and gas power stations is sensitive to grid disturbances, gas power stations which are connected to distribution network will produce a correspond impact on the grid. Therefore, it is important to study the control strategy of gas power station. In view of three kinds of operation modes of gas power generation stations in China, the island and anti-island effect of the distributed gas power stations connected to distribution network are discussed. Then the three kinds of anti-Island efficiency strategies are proposed for gas power generation, which are based on communication, synchronous generator and grid connected inverter, and their advantages and disadvantages are analyzed and compared. The three kinds of anti-Island benefit strategy have important reference and guidance for the design and operation of gas power stations in China. The model of mine gas generatorIgnore the rectifier loss and assume the output electromagnetic power of the rectifier equal to the magneto alternator. Based on the relation of rotate speed and power, the output electromagnetic torque of the generator Ignore the damping of the generator, the rotor motion formation of the generator:Therefore the simplified model integrates magneto alternator and rectifier is shown in Figure.1.

“…However, due to the strong nonlinearity of power electronic devices, SPVSC also brings about the problem of harmonic pollution which has a negative impact on power grid [5][6][7]. Hence, it is necessary to analyze the mechanism of harmonic injection and propose effective suppression measurements, laying a solid foundation for the promotion of SPVSC.…”

With the development of distributed generations (DGs), single-phase voltage source converter (SPVSC) has been widely used, but it brings about the problem of harmonic pollution to power grid. Hence, it is significant to explore the mechanism of harmonic injection from SPVSC and propose effective control strategies to mitigate the harmonic pollution. In this paper, a harmonic analysis model of SPVSC based on dynamic phasor (DP) has been established. With the model, the harmonics interaction between the ac side and the dc side can be analyzed with the consideration of the control strategies, which reveals the generation mechanism of the harmonics in SPVSC. Based on the mechanism, a feedforward harmonic mitigation strategy has been presented. The principle of the strategy is to add low-order harmonic signal to the PWM modulation signals to reduce the harmonic current on the ac side. The harmonic mitigation strategy not only has clear physical meaning and fast calculation, but also is robust for the uncertainty of parameters. Finally, the simulation and experiment results demonstrate the correctness of the model and the effectiveness of the harmonic mitigation strategy.
