具体实施方式Detailed ways
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.
本发明实施例一种光伏发电站的控制方法的实现流程，如图1所示， 包括以下步骤：An implementation flow of a control method for a photovoltaic power station according to an embodiment of the present invention is shown in FIG. Includes the following steps:
步骤S101，确定所述光伏发电站中第一发光单元的数量。Step S101, determining the number of the first lighting units in the photovoltaic power station.
这里，所述第一发光单元为用于留有备用容量的发光单元。Here, the first light emitting unit is a light emitting unit for leaving a spare capacity.
在一可选实施方式中，光伏发电站的控制装置确定所述光伏发电站中第一发光单元的数量的实现过程，如图2所示，包括以下步骤：In an alternative embodiment, the control device of the photovoltaic power station determines an implementation process of the number of first lighting units in the photovoltaic power station, as shown in FIG. 2, including the following steps:
步骤S1010，获取当前辐照度下，光伏发电站的最大输出功率。Step S1010: Acquire a maximum output power of the photovoltaic power station under the current irradiance.
在一可选实施方式中，首先采集当前辐照度下，光伏发电站所配备的每个发光单元当前最大功率点跟踪(Maximum Power Point Tracking，MPPT)输出的最大功率；再将全部发光单元当前MPPT输出的最大功率求和，得到当前辐照度下光伏发电站的最大输出功率。In an optional implementation manner, firstly, the maximum power of the maximum power point tracking (MPPT) output of each lighting unit provided by the photovoltaic power station under the current irradiance is collected; and then all the lighting units are currently The maximum power of the MPPT output is summed to obtain the maximum output power of the photovoltaic power station under the current irradiance.
可以看出，光伏发电站的实时发电量受太阳辐照度的影响，并且与辐照度成正比；在辐照度强时，光伏发电站的实时发电量大；在辐照度弱时，光伏发电站的实时发电量小。It can be seen that the real-time power generation of photovoltaic power plants is affected by solar irradiance and is proportional to the irradiance; when the irradiance is strong, the real-time power generation of the photovoltaic power station is large; when the irradiance is weak, The real-time power generation of photovoltaic power stations is small.
步骤S1011，基于所述光伏发电站的最大输出功率确定第一发光单元的数量。Step S1011, determining the number of the first lighting units based on the maximum output power of the photovoltaic power station.
在一可选实施方式中，光伏发电站的控制装置确定第一发光单元的数量的具体实现过程，如图3所示，包括以下步骤：In an alternative embodiment, the control device of the photovoltaic power station determines a specific implementation process of the number of first lighting units, as shown in FIG. 3, including the following steps:
步骤1a，确定备用容量。In step 1a, the spare capacity is determined.
这里，确定光伏发电站的最大输出功率与备用系数之积为备用容量；即：备用容量＝光伏发电站的最大输出功率*备用系数K。Here, it is determined that the product of the maximum output power of the photovoltaic power station and the standby coefficient is the standby capacity; that is, the spare capacity = the maximum output power of the photovoltaic power station * the standby coefficient K.
其中，备用系数K的值可根据实际情况进行设定；在一优选实施例中，设定K的值为10％。The value of the standby coefficient K can be set according to actual conditions; in a preferred embodiment, the value of K is set to 10%.
步骤1b，检测当前辐照度下，发光单元的输出功率。In step 1b, the output power of the light emitting unit under the current irradiance is detected.
这里，发光单元的输出功率为当前辐照度下，所有发光单元的输出功率。 Here, the output power of the light emitting unit is the output power of all the light emitting units under the current irradiance.
步骤1c，根本备用容量及逆变器的输出功率确定第一发光单元的数量。In step 1c, the fundamental spare capacity and the output power of the inverter determine the number of first lighting units.
在一可选实施方式中，第一发光单元的数量＝备用容量/发光单元的输出功率。In an alternative embodiment, the number of first lighting units = the spare capacity / the output power of the lighting unit.
这里，发光单元的输出功率为当前辐照度下，所有发光单元的输出功率。Here, the output power of the light emitting unit is the output power of all the light emitting units under the current irradiance.
步骤S102，控制第一发光单元处于热备用状态。Step S102, controlling the first lighting unit to be in a hot standby state.
基于图2及图3所示的流程，已经确定了第一发光单元的数量，这里，光伏发电站的控制装置控制所述第一发光单元处于热备用状态。Based on the flow shown in Figures 2 and 3, the number of first lighting units has been determined, where the control device of the photovoltaic power station controls the first lighting unit to be in a hot standby state.
处于热备用状态的发光单元的电源侧(母线)带电，断路器在开位，但两侧的隔离开关均在合位；断路器一经合闸，即可将电送出。The power supply side (busbar) of the lighting unit in the hot standby state is energized, the circuit breaker is in the open position, but the isolating switches on both sides are in the same position; once the circuit breaker is closed, the electricity can be sent out.
步骤S103，检测光伏发电站工作时的频率。Step S103, detecting the frequency at which the photovoltaic power station operates.
在一可选实施方式中，光伏发电站的控制装置通过从光伏发电站站桩的电压互感器的输入，得到实时的光伏发电站的电压信息；根据电压信息计算光伏发电站运行时的频率和频率变化率。In an optional implementation manner, the control device of the photovoltaic power station obtains the voltage information of the real-time photovoltaic power station by inputting the voltage transformer from the photovoltaic power station pile; calculating the frequency of the photovoltaic power station operation according to the voltage information Frequency change rate.
其中，频率瞬时值通过采集电压波形即可计算，即采集电压信号，f＝1/(t*2)，t为电压波形中每2个过零点之间的时间间隔。Among them, the instantaneous value of the frequency can be calculated by collecting the voltage waveform, that is, the voltage signal is acquired, f=1/(t*2), and t is the time interval between every two zero-crossing points in the voltage waveform.
频率变化率即频率的变化速度

实际操作中可每秒计算一次或更短的时间，即(f2-f1)/t，(t为f2和f1之间的时间间隔)。Frequency change rate
Figure PCTCN2017101659-appb-000001
In practice, it can be calculated once or less per second, ie (f2-f1)/t, (t is the time interval between f2 and f1).
步骤S104，基于光伏发电站频率控制光伏发电站中发光单元的工作状态。Step S104, controlling an operating state of the light emitting unit in the photovoltaic power station based on the frequency of the photovoltaic power station.
