Description

  The present invention relates to a management operation device and a management operation method for a pump station, and in particular, an unmanned drainage pump station and a solar power generation device, and by performing solar power generation, an electrically self-supporting pump station that does not receive commercial power The present invention relates to a preferred management operation apparatus and management operation method.

  In a pump station such as a drainage pump station, the power source configuration is generally a configuration that employs a commercial power source and a private power generator. Moreover, when the normal management power supply capacity of the pump station is small, it is possible to adopt a solar power generation device and to make the pump station electrically independent by omitting the commercial power source. However, even in such an electrically self-supporting pumping station, the capacity of the storage battery is reduced, such as when sufficient sunshine hours cannot be obtained, or when the solar power generation device fails, and the control power supply, pump device or power generation It may be impossible to start the prime mover of the device.

  Therefore, conventionally, a management operation is periodically performed to generate power by operating a power generation device, and a pump device is operated with the generated power to charge a storage battery. Further, even when a photovoltaic power generation device is provided to make up for the spontaneous discharge of the storage battery, a commercial power supply is required as a backup due to reliability problems.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a management operation device and a management operation method capable of performing a highly reliable management operation that is electrically independent and suitable for an unmanned pump station. .

  In order to solve the above problems, the invention described in claim 1 includes a pump device, a power generation device, and a storage battery, supplies power necessary for starting from the storage battery to the power generation device at a predetermined timing, and starts the power generation device. In a management operation device of a pump station that includes a management operation control means for performing a management operation for supplying and charging at least the generated power to the storage battery, a storage battery remaining capacity sensor is provided for detecting the remaining capacity of the storage battery. The management operation control means has a function of performing a management operation when the storage battery remaining capacity becomes a predetermined value from the output of the storage battery remaining capacity sensor.

  According to a second aspect of the present invention, in the management operation device for a pump station according to the first aspect, the storage battery supplies a starting storage battery for supplying power for starting the pump device or the generator, and supplies power to various instrumentation devices. A control power storage battery is provided, and the management operation control means performs the management operation when the remaining capacity of at least one storage battery reaches a predetermined value.

  The invention according to claim 3 is the management operation device for the pump station according to claim 1 or 2, wherein the storage battery remaining capacity sensor monitors the charge / discharge current, voltage, temperature, and discharge time of the storage battery to determine the remaining capacity. It is a sensor to detect.

  The invention according to claim 4 includes a pump device, a power generation device, and a storage battery, supplies power necessary for starting from the storage battery to the power generation device at a predetermined timing, activates the power generation device to generate power, In a management operation method of a pump station that performs a management operation for supplying and charging at least the generated power to the storage battery, the management operation is performed when the remaining capacity of the storage battery reaches a predetermined value.

  According to the invention described in claim 1, since the management operation control means has a function of performing the management operation when the storage battery remaining capacity reaches a predetermined value, the management operation can be performed at a timing based on the storage battery remaining capacity, The management operation cannot be executed because the remaining capacity of the storage battery is too small, and the management operation with high reliability becomes possible. For example, a management operation device suitable for an unmanned and electrically independent drainage pump station can be provided.

  According to the invention described in claim 2, the management operation control means performs the management operation when the remaining battery capacity of either the starting storage battery or the control power storage battery reaches a predetermined value, thereby further improving the reliability. A management operation device capable of high management operation can be provided.

  According to the invention described in claim 3, the storage battery remaining capacity sensor detects the remaining capacity by monitoring the charge / discharge current, voltage, temperature, and discharge time of the storage battery, so the remaining capacity is estimated only by the voltage of the storage battery. Unlike the case where it does, since the storage battery remaining capacity can be detected accurately, a more reliable management operation is possible.

  According to the fourth aspect of the invention, since the management operation is performed when the remaining capacity of the storage battery reaches a predetermined value, the remaining capacity of the storage battery is not so small that the management operation cannot be performed, and the management is highly reliable. Operation becomes possible, for example, it is possible to provide a management operation method suitable for an unmanned and electrically independent drainage pump station.
