Description

Technical Field

[0001] The present invention relates to the field of compressed air energy storage power station control technology, more specifically, it is a compressed air energy storage power station control system architecture. The present invention also relates to a control method of the compressed air energy storage power station control system architecture. Background Art

[0002] Compressed air energy storage, as a new energy storage technology, will play an increasingly important role in the construction of new power systems. Its main application scenarios are peak shaving and valley filling, renewable energy consumption on the power supply side, grid auxiliary services, and user-side services.

[0003] Since compressed air energy storage power stations are still in their infancy, the design schemes tend to be more mature and reliable, and control system manufacturers have not yet proposed better solutions for the control characteristics of compressed air energy storage. For the electrical systems of the built compressed air energy storage power stations, most of them refer to the control mode of traditional thermal power, and the high-voltage distribution device is independently controlled by the power network computer monitoring system (NCS). The plant power supply can be controlled by the electrical monitoring and management system (ECMS), or it can be included in the DCS control. The generator-transformer group and the machine and furnace linkage part are controlled by DCS, and other monitoring signals can be connected to DCS or ECMS. For the thermal system, the compressor uses the manufacturer's own compressor control system (CCS), the turbine uses the manufacturer's own digital electro-hydraulic control system (DEH), and the heat storage and auxiliary system is equipped with a DCS control system. The control system networks are independent, the hardware is not unified, and the communication protocols are diverse and difficult to integrate. Data sharing of the entire station has not been achieved, which also causes inconvenience to the subsequent development and operation and maintenance of advanced applications on site.

[0004] Since the process system of compressed air energy storage power station is relatively simple, and its operation process is closely related to power grid dispatch, it has high requirements in terms of high flexibility, rapid response, and bidirectional adjustment. Therefore, it is necessary to develop a control system architecture and control method that can meet the safe, reliable, and efficient control of compressed air energy storage power station.

The generator-transformer set system of the electrical system detects that the grid-connected conditions are met and then executes the grid-connected operation, and the expansion energy release process ends.

[0032] Compared with the prior art, the present invention has the following advantages:

[0033] 1) The present invention sets up a telecontrol host at the station control layer and utilizes the network architecture to collect information from the entire station, thereby completing the dispatching of all telecontrol function requirements such as telemetry, telesignaling, teleadjustment, and remote control for the compression control energy storage power station; thereby eliminating the cost of setting up a separate telecontrol system and avoiding the work of repeated data collection.

[0034] 2) The present invention adopts IEC61850 as the basis for formulating the telecontrol seamless communication system of the power system, which can greatly improve the equipment data integration of information technology and automation technology, reduce the cost of engineering, on-site acceptance, operation, monitoring, diagnosis and maintenance, save a lot of time, and increase the flexibility of the automation system during use.

[0035] 3) The electrical system of the present invention adopts a protection measurement and control device to realize data collection, and can use the IEC61850 protocol at the interval layer to achieve the unification of software and hardware.

[0036] 4) The thermal system of the present invention adopts DPU as a data processor at the interval layer according to its decentralized control characteristics, thus realizing hardware unification and facilitating the implementation of the whole station control optimization strategy; the thermal control is not limited to the communication protocol at the interval layer, and is connected to the station control layer network after being converted into the IEC61850 communication protocol by the communication interface machine, which has universal applicability; the operator station of the thermal system is retained, realizing decentralized control and centralized management of the thermal system; the thermal system only transmits necessary signals to the station control layer to reduce data redundancy.

[0037] 5) The present invention meets the characteristics of data processing of electrical systems and thermal control systems. Because the control and locking logic of the electrical system is relatively simple, the control frequency of electrical equipment is low, the installation environment of electrical equipment is good and the layout is relatively concentrated, the electrical data is concentrated on the station control layer server for processing; because the thermal control system focuses on the process control of the process system, the control location is relatively scattered, and DPU as a data processor can well meet this requirement.

[0038] 6) Through the present invention, the information of the entire station can be centrally managed and analyzed at the station control layer, which well realizes the intelligent operation and maintenance of status monitoring, fault diagnosis and status analysis; it can realize the use of advanced functions such as simulation training and operation guidance for operators based on the information of the entire station, while ensuring the safe and reliable operation of the units, maximizing the social and economic benefits of the power station.

[0056] The data processing and control logic of the electrical system bay layer equipment 211 are all centralized in the system server 120 of the station control layer 100, which reduces the interface coordination work between the hardware equipment of each electrical system and improves the reliability of the system;

[0057] The data processing and control logic of the thermal system isolation layer equipment 221 are distributed in the data processors 223 of each process system of the thermal system isolation layer equipment 221, which can not only meet the monitoring requirements of each process system, but also avoid the system server 120 of the station control layer 100 processing too much data and causing system congestion.
