在具体的实际应用中，可以通过采用数值模拟分析为工程实体设计提供参考，提高装备的性能。具体的，可以采用多物理场仿真软件COMSOL进行模拟分析。在既有电源装备条件下，对绝缘槽2内电极结构参数进行分析和优化，以满足绝缘槽2内电场数值在1KV/cm以上。所述高压脉冲电源的参数具体可以设置如下：输入电压为交流220V，输入功率最大2KW，最大工作频率200Hz，输出电压50KV，输出脉冲宽度为1μs。In specific practical applications, numerical simulation analysis can be used to provide reference for the design of engineering entities and improve the performance of equipment. Specifically, the multi-physics simulation software COMSOL can be used for simulation analysis. Under the condition of the existing power supply equipment, the structural parameters of the electrodes in the insulating tank 2 are analyzed and optimized to meet the value of the electric field in the insulating tank 2 above 1KV/cm. The parameters of the high-voltage pulse power supply can be specifically set as follows: the input voltage is AC 220V, the maximum input power is 2KW, the maximum operating frequency is 200Hz, the output voltage is 50KV, and the output pulse width is 1μs.
在上述参数设置下，可使得绝缘槽2内电场分布近似为均匀场，其电场方向为由带正电的导电针棒6指向对面的接地的阴极板3。该电场随与导电针棒6的距离的增加，更趋向均匀，整个腔体场强范围为：1.0KV/cm～2.0KV/cm之间。通过仿真，可以得到在导电针棒6指向对面的接地的阴极板3的方向上，由导电针棒6远离阳极板1的端点开始，其0.3m的截面内电场分布为1.32KV/cm～1.33KV/cm，可见电场分布基本是均匀的。且以上结构装置参数设定可以满足预期所要求的电场大于1KV/cm。Under the setting of the above parameters, the electric field distribution in the insulating tank 2 can be approximated as a uniform field, and the direction of the electric field is from the positively charged conductive needle bar 6 to the opposite grounded cathode plate 3 . The electric field tends to be more uniform with the increase of the distance from the conductive needle bar 6, and the electric field strength range of the whole cavity is: 1.0KV/cm-2.0KV/cm. Through simulation, it can be obtained that in the direction of the conductive needle bar 6 pointing to the opposite grounded cathode plate 3, starting from the end point of the conductive needle bar 6 away from the anode plate 1, the electric field distribution in the 0.3m section is 1.32KV/cm～1.33 KV/cm, it can be seen that the electric field distribution is basically uniform. And the parameter setting of the above structural device can meet the expected electric field greater than 1KV/cm.
优选的，所述高压脉冲电源为固态开关型高压脉冲电源。Preferably, the high-voltage pulse power supply is a solid-state switching high-voltage pulse power supply.
针对该应用环境中电压需求很高(几千伏～几十千伏)，而瞬时电流很小(几mA～几百mA)，而且放电时间很短，在发生介质放电之前达到所需电场要求，每秒钟发生的脉冲数量仅有几个至几十个，单个脉冲脉宽为几微妙至二十微妙，从而系统总功率不大，不属于脉冲功率范畴。基于此所述高压脉冲电源采用固态开关型高压脉冲电源即可，其主要功能结构包含高压脉冲储能功能、驱动功能、动态均压功能、以CPU为核心的控制功能、过流以及短路保护功能等，此处不做具体限定，可以视其具体应用环境而进行相应的选用。For this application environment, the voltage requirement is very high (several thousand volts to tens of thousand volts), but the instantaneous current is small (several mA to hundreds of mA), and the discharge time is very short, so that the required electric field requirements can be reached before dielectric discharge occurs , the number of pulses generated per second is only a few to dozens, and the pulse width of a single pulse is several microseconds to twenty microseconds, so the total power of the system is not large, and it does not belong to the category of pulse power. Based on this, the high-voltage pulse power supply can be a solid-state switch-type high-voltage pulse power supply. Its main functional structure includes high-voltage pulse energy storage function, driving function, dynamic voltage equalization function, control function with CPU as the core, over-current and short-circuit protection functions. etc., are not specifically limited here, and can be selected according to the specific application environment.
需要说明的是，本发明实施例提供的级联型光伏逆变器的并网控制方法实现了功率电容上的电压自平衡的功能，可以理解的是，由该级联型光伏逆变器的并网控制方法组成的三相三线制以及三相四线制级联型光伏逆变器的并网控制方法同样具有该优点。It should be noted that the grid-connected control method of the cascaded photovoltaic inverter provided by the embodiment of the present invention realizes the voltage self-balancing function on the power capacitor. It can be understood that the cascaded photovoltaic inverter The grid-connected control method of the three-phase three-wire system and the three-phase four-wire system cascaded photovoltaic inverter composed of the grid-connected control method also has this advantage.
