The design of photovoltaic power station monitoring system should follow the following principles:
(1) Integrity
The system can complete the unified and complete collection of monitoring data from different manufacturers, different types and models of equipment, and can provide application services for real-time data, periodic sampling data, and event data.
(2) Normative
The system construction follows relevant national standards, international standards, and relevant standards of the power industry, formulates or improves relevant standards and specifications to ensure the standardization of monitoring equipment and monitoring data communication, and the interface design follows the relevant interface design specifications.
(3) Scalability
Hardware scalability; the system can be widely adapted to the communication interface of new access monitoring equipment; software scalability: software function modules should be reusable, configurable and detachable.
(4) Openness
The system can exchange data and information with various expert systems, and the system can exchange data and information with systems such as power grid dispatching.
(5) Integration
It can integrate monitoring data such as environment, security, electric energy, power quality, etc., classify processing, classify storage, and display monitoring data in a unified interface.
(6) Operability
Friendly interface, easy operation, focus on user experience.
(7) Adaptability
Adapt to the complexity of the internal electromagnetic and natural environment of photovoltaic power plants. Adapt to the accessibility of various systems of photovoltaic power plants.
The photovoltaic power station monitoring system should be able to realize reliable, reasonable and complete monitoring, measurement and control of the power station, and have all the motion functions such as telemetry, remote signaling, forced adjustment, forced control, etc., and should have the ability to exchange with the computer system of the superior dispatch center. information capacity.
