Therefore, it is necessary to develop a visualized transmission parameter management system.

从而对提高调度效率和提高电网运行的安全性、可靠性有着重大的现实意义。

The second part is mainly about discussion on accurate equivalents of electronic power networks.

第二部分主要是关于电网精确等值的讨论。

Type of permanent magnet bodies ZN73M vacuum circuit breaker for indoor installation, air-insulated, for the opening and closing of the different nature of the power load for the city network, rural power grid, power grids, such as mining and railroad construction and renovation projects, especially used in the current scope of operations and the frequent breaking of the short-circuit operation required a certain number of occasions.

ZN73M型永磁机构真空断路器为户内安装、空气绝缘，用于开合各种不同性质的电力负荷，适用于城网、农网、矿山及铁道等电网建设和改造工程中，尢其是用于在工作电流范围内频繁操作和对短路开断操作次数有一定要求的场合。

The internal armature winding fault of synchronous generator、which is common and destructive, greatly affects the security of the generator and the power network.

同步发电机定子绕组内部故障是一种常见的、破坏性很强的故障，对电厂发电机乃至电网的安全运行都将带来一系列严重的影响。

Therefore, the article takes the study in-depth of three-phase unbalanced load compensation for the balance of theory, hold a proposed compensation algorithm based dq transformation, and designs a system to improve the power grid with the function of three-phase unbalance compensation.

所以，文章在深入研究三相不平衡负荷的平衡化补偿原理的基础上，提出了基于dq变换的补偿算法，并设计了具有改善电网三相不平衡功能的补偿系统。

At the same time, the company also has production JP low-voltage distribution cabinets, power station control cabinet and all kinds of distribution box, and is supporting the transformation of rural power equipment manufacturing plant, the company has a casting factory, with a large cupola furnace, Mixer, Shot casting machines and other equipment and testing equipment, capable of producing various grades of gray cast iron, wear-resistant cast iron, ductile iron castings.

同时公司还具备生产JP低压配电柜，电站控制柜及各种配电箱的能力，是农村电网改造配套设备的生产厂，公司设有铸造分厂，具有大型化铁炉，混砂机，喷丸机等铸造设备和检测设备，能生产各种牌号的灰口铸铁、耐磨铸铁、球墨铸铁铸件。

The system includes the modules of graphic interface, parameter and setting management, short current calculation, and breaker status simulation.

应用面向对象的编程技术，研制成功电网拓扑图形与后台数据库相结合的继电保护开关状态仿真系统。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
