Problems solved by technology

In addition, under the current technical means and management methods, the performance of some regulation systems in power plants still does not meet the standards; the performance indicators of various functions of the unit regulation systems of some power plants are not perfect, and the overall response characteristics of the power grid are not considered
Coupled with the reform of the power system, the state implements the separation of power plants and power grids, and power grid companies cannot restrict the behavior of the power supply side according to administrative orders, resulting in loose coordination of network sources

Embodiment Construction

[0043] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and through specific embodiments.

[0044] figure 1 It is a schematic diagram of the system structure of the machine-network coordination system. It mainly includes thermal power plant substation acquisition system, hydropower station substation acquisition system, wind farm substation acquisition system and central master station system. The thermal power plant substation acquisition system, hydropower substation acquisition system, and wind farm substation acquisition system send the substation real-time data and wave recording files to the front-end server of the central master station system through the standard IEC104 protocol by means of the power dispatching data network. The front-end server is deployed in the security zone II, and the other master servers are deployed in the security zone III. Due to the cross-zone data shuttl...

Abstract

The invention discloses a unit network coordination system based on high-capacity multivariate data access. The system comprises a thermal power plant sub-station acquisition system, a hydraulic power plant sub-station acquisition system, a wind farm sub-station acquisition system, and a central main station system, and the thermal power plant sub-station acquisition system, the hydraulic power plant sub-station acquisition system, the wind farm sub-station acquisition system, and the central main station system realize communication via an IEC104 protocol and a power dispatching data network. Based on the system, centralized acquisition of data of a professional equipment stage and a control system stage such as thermo-technology, water machines, and excitation at a power grid side of a thermal power plant is realized, and with the combination of power grid operation information, advanced application functions of unit network coordination such as operation equipment evaluation of equipment at a generation side and network involvement function examination are realized.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to providing a machine-network coordination remote monitoring, evaluating and diagnosing platform for power grid companies. Background technique [0002] Power supply and power grid are integral parts of the power system, and both have equal obligations and responsibilities for the safety of the power system. With the formation of the national AC-DC UHV interconnected grid, the grid scale and power generation capacity are growing rapidly. The characteristics of the power grid are becoming more and more complex, the operation mode is changeable, the accidents of the power grid are widely spread, and the mechanism is complex. The regulation characteristics and operation status of the generator have an increasingly significant impact on the safe and stable operation of the system. In addition, under the current technical means and management methods, the performance ...
