Description

Technical Field

[0001] The invention belongs to the technical field of power transmission and transformation engineering, and in particular relates to a mass data storage device for a digital handover system of a power transmission and transformation engineering. Background Art

[0002] An important indicator for dynamic economic evaluation of power engineering projects is the internal rate of return, also known as the internal rate of return. This indicator takes into account the time value of money and intuitively reflects the maximum possible profitability of power engineering project investment. This indicator is determined by the endogenous cash flow characteristics and is completely based on the cash flow specified by the internal conditions of the power engineering project. It reflects the pure profitability of the power engineering project itself, so it is called the internal rate of return.

[0003] Unlike net present value and net annual value, this indicator does not require a base discount rate to be set in advance before calculation. Therefore, when conducting economic evaluation of power engineering projects in my country, the internal rate of return is used as a major indicator. However, due to the cumbersome calculation process of the internal rate of return, there may be no solution or multiple solutions in unconventional projects, which causes some inconvenience in practical applications. This involves generating a large amount of data as a basis for the next step of research and development.

[0004] Digital handover is to construct the engineering project digitally in the form of models and numbers, so as to reflect the system structure more intuitively and conveniently. The establishment of the digital handover system is more convenient in function display and control than the traditional handover work, and the system status can be observed intuitively.

[0005] Transmission and transformation projects are a general term for transmission line construction and transformer installation projects. The higher the voltage level of the transmission and transformation project, the greater the power transmitted and the longer the transmission distance. Transmission and transformation projects with voltages exceeding 330,000 volts are called ultra-high voltage transmission and transformation. At present, the highest voltage level of ultra-high voltage transmission and transformation lines put into operation in my country is ±1100kV DC transmission lines and 1000kV AC transmission lines.

[0006] During the construction of power transmission and transformation projects, due to the huge size of the system, the number of nodes in the digital handover system is huge, and there are many equipment models. Therefore, the amount of system data is huge, which requires huge storage space.

[0007] The existing massive data storage device of the digital handover system, such as the application number CN202020337507.7 “A massive data storage device of the digital handover system of power transmission and transformation project”, is “comprising a control unit and a storage unit, wherein a plurality of storage units are arranged in parallel and are electrically connected to the control unit, and the control unit is provided with a data interface for connecting to an external host. After the control unit is connected to the external host, the input data is respectively input into the storage unit…”. Although it solves the problem of multiple independent systems, the positions of multiple independent systems cannot be adjusted, resulting in the installation space required for different data not being consistent with the designed space, and the installation requirements cannot be met. Moreover, it cannot be individually and specifically repaired, but requires large-scale maintenance, which is very difficult. Summary of the invention
