Description

An energy storage power station monitoring system

technical field

The invention relates to a monitoring system in the technical field of automatic control of an energy storage system, in particular to a monitoring system for an energy storage power station.

Background technique

The power production process is continuous, and the power generation-transmission-transformation-distribution-power consumption must be kept in balance at all times. Production and consumption are required to be completed at the same time. Instantaneous imbalances may lead to security and stability problems. However, there are large differences in the power demand of users in the power grid between day and night and different seasons, which makes the power system must have a large reserve capacity, and the operating efficiency of the system equipment is low. The application of energy storage technology can achieve peak shaving and valley filling, improve system reliability and stability, and reduce system backup requirements and power failure losses. In addition, with the increasing scale of new energy power generation and the continuous development of distributed power generation technology, the importance of power storage systems has become increasingly prominent.

The application of energy storage technology is to add a link of "storage" electric energy on the basis of the traditional power system production mode, so that the original almost completely "rigid" system becomes "flexible", and the safety, reliability and economy of power grid operation , Flexibility will thus be greatly improved. Therefore, some people regard energy storage technology as the "sixth link" in the process of electric power production, and the application prospect of electric energy storage technology is very broad.

The use of fossil energy will also bring serious environmental pollution and make the climate abnormal. Insufficient energy supply has become the bottleneck of global economic development. At the same time, the environmental pollution caused by the use of fossil energy has been highly valued by the world. Actively developing alternative new energy and energy storage technologies to reduce human dependence on fossil resources has become a hot research topic in the industry and science and technology circles. Among renewable energy sources, wind energy and solar energy have attracted the attention of the industry in particular. One is that the sources are abundant, inexhaustible and inexhaustible, and the other is that they do not pollute the environment or pollute very little in the process of utilization. However, they also have common defects, namely intermittent, unstable and uncontrollable. In order to ensure the balance and continuity of power supply, energy storage has become a key supporting component of wind and solar power generation systems. Therefore, while utilizing solar and wind energy, attention must be paid to the development of energy storage technology.

Today's society has higher and higher requirements for the quality, safety and reliability of energy and power supply. The traditional large power grid power supply method can no longer meet this requirement due to its own defects. In large-scale interconnected power systems, local accidents are easy to spread, and centralized large power grids cannot flexibly track changes in power loads. At present, the combination of large power grid and distributed generation is recognized by many energy and power experts in the world as the main method that can save investment, reduce energy consumption, improve system security and flexibility, and is the development direction of the power industry in the 21st century. Distributed generation refers to the arrangement of smaller generating units directly on the distribution network or distributed near the load to meet the needs of specific users or support the economic operation of the existing distribution network. Distributed power generation includes micro gas turbines, fuel cells, renewable energy such as solar power and wind power, etc. Based on the consideration of system stability and economy, the distributed generation system needs to store a certain amount of electric energy to deal with emergencies. With the development of power electronics, materials science and other disciplines, modern energy storage technology has been developed to a certain extent, and has played an important role in distributed power generation, such as: improving power quality and maintaining system stability; in distributed power generation Provide power to users during the period when power generation is not available; improve the economic benefits of investors in distributed power generation units.

Energy storage technologies mainly include physical energy storage (such as pumped water storage, compressed air energy storage, flywheel energy storage, etc.), chemical energy storage (such as various batteries, renewable fuel cells, liquid flow batteries, supercapacitors, etc.) and electromagnetic energy storage. Energy (such as superconducting electromagnetic energy storage, etc.), etc., the present invention is mainly oriented to the application of chemical or electromagnetic energy storage systems (power stations) in power systems. With the continuous application of energy storage systems (power stations), it is necessary to monitor, control and manage energy storage power stations/systems to ensure the safe and reliable operation of energy storage power stations/systems.
