Problems solved by technology

A large number of harmonic currents will cause voltage distortion in the grid, seriously endangering the stability of the grid operation
At the same time, a large number of harmonics accumulate and superimpose in the power grid, resulting in increased line loss and wasted power

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the drawings and embodiments.

[0029] Such as figure 1 with figure 2 , A power system energy efficiency test management system, the whole system is divided into three layers:

[0030] The first layer is the network management layer, which centrally manages the PXI or IPC / PC104 master computer through the server, and forms the Ethernet LAN through the hub, which is cascaded to other LANs to realize network management, including user management and the allocation of shared resources.

[0031] The second layer is a PXI system or IPC / PC104 system equipped with an embedded controller. On the one hand, it acts as the client of the centralized management system, and on the other hand, it is the master computer of the field measurement and control equipment, which acts as a gateway. The main application programs of this layer are divided into two categories. The main function of one category is to organize and...

Abstract

The invention discloses a power system energy efficiency test management system and a test method. The whole system includes three layers, the first layer is a network management layer, a PXI or IPC / PC104 main control computer is managed in a centralized manner by a server, and an Ethernet local area network is formed by a concentrator and cascaded to other local area networks. The second layer is a measurement and control layer provided with a PXI system or IPC / PC104 system of an embedded controller, serves as a client of a centralized management system, also serves as a main control computer for on-site measurement and control equipment and functions as a gateway. The third layer comprises various monitoring and test equipment units mounted on an operation site of monitored equipment, and the types and the number of the units are determined according to monitoring requirements. Remote energy consumption real-time dynamic monitoring, energy consumption management and energy efficiency analysis work for power equipment at all levels of a power system are realized, and real-time energy management and energy consumption of the power system are realized.

Description

Technical field [0001] The invention relates to the technical field of power system energy saving, in particular to a power system energy efficiency test management system and a test method. Background technique [0002] In recent years, energy conservation, environmental protection, and climate change have become the focus of universal attention in countries all over the world. Energy conservation, improvement of energy efficiency and development of renewable energy have also become one of the basic energy development strategies of all countries in the world. In the face of increasing energy shortages, various countries have launched a series of measures to improve energy efficiency, save energy and reduce consumption. [0003] The power industry is one of the key areas for energy saving and consumption reduction. The strong smart grid plays the role of "peak shaving and filling valley" to reduce power installations, thereby reducing investment in power generation companies; impro...
