Solar cathodic protection system

At present, in the pipeline construction, especially in the construction of long-distance pipelines in Western and remote areas, most of the valve chambers, cathodic protection stations and communication relay stations along the pipeline are built in areas with poor environment and sparsely populated population. The distance between stations is far and it is not convenient to use AC power. The power supply of the equipment becomes a major problem.

Alternative energy sources are usually used in the design, and the power supply equipment is generally as follows:

(1) Rectifier equipment of AC mains power supply (potentiostat, rectifier, galvanostat);

(2) Thermoelectric generator (TEG);

(3) Closed cycle steam generator (CCVT);

(4) Wind turbine;

(5) Solar cells;

(6) Large capacity battery, etc.

In the above several kinds of power supply, there are some special requirements for the site conditions, so the most used solar cells are solar cells.

The solar power system consists of solar cells, batteries, system controller and so on. Solar cell is a device that uses photovoltaic effect of materials to convert light energy into electrical energy directly. Several solar cell modules are installed outdoors after series and parallel connection. As a power supply device, the solar cell should be used together with the battery. The battery plays the role of energy storage, energy supply and system voltage regulation in the system, so as to ensure the power supply at night or in cloudy days when there is no sun.

The system controller, which is composed of interface circuit and software system, is the core to ensure the normal and reliable operation of the system. It can control and manage the charging and discharging of the battery and the load, so as to ensure that the load can get enough current at any time, decide when to put the solar cell and the possible standby generator into or off, and maintain the battery working in the best state, and extend the storage battery as far as possible Battery life. The interface circuit has a serial communication interface with the remote PC, which can realize the remote control of data.
