Abstract

PURPOSE:To improve the operation efficiency of a solar battery by utilizing excessive electric power as a pump power source. CONSTITUTION:The series circuit of a chopper 10 and a DC motor 11 for pump driving is connected to a DC circuit at an inverter input side in parallel and the current obtained by subtracting an inverter input current corresponding to load electric power and the charging current of the solar battery 4 from the output current of a solar battery array 2 is shunt to said parallel circuit in a time zone in which excessive electric power is generated. The voltage- current characteristic of the solar battery array 2 varies with the quantity of solar radiation, but a voltage VP at which maximum electric power is obtained is nearly constant, so the output current of the solar battery array is only controlled so as to obtain the voltage VP, thereby obtaining maximum electric power corresponding to the quantity of solar radiation from the solar batteries. Specially, when the quantity of solar radiation is large and a storage battery 4 is charged to its limit, the excessive electric power is large, but this is utilized as the driving electric power of a motor-driven pump to realize operation with the maximum electric power of the solar battery array.

Particularly in developing countries with inadequate power systems, diesel power generation is often used, but due to rising fuel consumption costs, operating costs are high, and the inconvenience of limiting operating hours is forced to save fuel. In many cases, solar power generation and diesel power generation are combined (= saving fuel and reducing power generation time).

In an electric pump to be driven, it is conceivable to connect the motor circuit in parallel (two connections) with the load 7. In that case, the inverter capacity needs to be increased to withstand the starting inrush current (== the starting inrush current) of the pump motor.

2. It changes depending on the amount of solar radiation, but since the voltage V, which gives the maximum power, is constant, in order to extract the maximum power from the solar cell according to the amount of solar radiation (2. All you have to do is control the output current of the battery array (Second, especially)
2When the amount of solar radiation is large and the storage battery 4 is at its charging limit (2), the surplus power becomes large, but this is used as the drive power of the electric pump (
1) to enable operation of the solar cell array at maximum power. In this case, the chopper may be of a known step-down type, and the input current of the chopper is set to voltage V, l.
By controlling the power to be constant, the electric pump is controlled at variable speed according to the surplus power.

Figure 3a) shows the head curve (rotational speed n, ~ns + nt > n2 > n3) and resistance curve (operating points are indicated by discharge it Q-, Q2, Q-) of the centrifugal pump during variable speed operation. ). In the case of a centrifugal pump, discharge pressure H1 discharge amount Q
, rotational speed n (=, Hoc n”, Q oc
There is a relationship of n. Therefore, it shows a good fit with the resistance curve in the case of pumping water from shallow wells, lakes, and rivers where the hot water rate is small.Thus, the solar power generation pattern has a higher resistance curve than the load pattern, and the storage battery has a charging limit (U.S. A variable speed drive electric pump (
= Utilization (Secondly, the operational efficiency of the solar power generation system can be improved.

。However, when applying an electric pump to a deep well with a large head H6, the discharge pressure of a centrifugal pump is proportional to the square of the rotation speed, so a slight decrease in the constantly changing surplus power can significantly increase the discharge volume. This is not desirable because it reduces the

2. The discharge pressure H has the characteristic that it is directly proportional to the rotation speed n. Therefore, even if the surplus power decreases and the rotation speed becomes low,
It is possible to obtain a corresponding discharge amount.
