SQ-300i-8700700-004 混合自动电压控制

SQ-300i-8700700-004是一款混合自动电压控制（HAVC）是一种针对电力系统的管理与调控分层的性质而设计的控制方法。它结合了工程数学理论和混杂系统的理念，实现了电力系统的电压分层调节和控制。

HAVC在原有的自动电压控制（AVC）功能基础上进行了扩展和提升。AVC主要关注在系统电压变化时，自动调节励磁以维持机端电压不变。而HAVC则进一步将这一功能扩展到了整个电网范围，并加入了更多的优化和控制目标，如电压水平、电压动态品质、电压稳定性和运行的经济性等。

HAVC的特点之一是它针对电力系统的管理与调控分层的性质进行设计。它采用了分层的结构，包括最高层、中间层和基层。这种结构使得控制指令能够离散地传递，并且可以根据需要响应“离散事件”。同时，基层控制器可以接收中间层的综合优化控制方案，通过反馈控制执行控制指令，完成最终的目标。

此外，HAVC还具有一些重要的差异和优势。与传统的二级电压控制方案相比，HAVC系统是由事件驱动的，控制指令直接响应于事件并消除该事件，而不是按照设定的时间启动。这使得HAVC系统更加灵活和高效。另外，HAVC系统的分层结构使得最高层和中间层各司其职，各自拥有本层的SCADA系统和数据库以及分析处理软件，从而降低了分析和处理数据的计算复杂程度，提高了调控速度和有效性。

总的来说，SQ-300i-8700700-004是一种先进的电力系统电压控制方法，它通过综合运用数学理论、混杂系统理念和分层控制结构，实现了对电力系统电压的精确、高效和优化控制。

The SQ-300i-8700700-004 is a hybrid automatic voltage control (HAVC) which is a control method designed for the hierarchical nature of power system management and regulation. It combines the theory of engineering mathematics and the concept of hybrid system to realize the voltage regulation and control of power system.

HAVC extends and enhances the original automatic voltage control (AVC) function. AVC is mainly concerned with automatically adjusting the excitation to maintain the machine terminal voltage when the system voltage changes. HAVC further extends this function to the whole grid, and adds more optimization and control objectives, such as voltage level, voltage dynamic quality, voltage stability and operation economy.

One of the characteristics of HAVC is that it is designed for the hierarchical nature of power system management and regulation. It adopts a hierarchical structure, including the top layer, the middle layer and the base layer. This structure allows control instructions to be passed discretely and can respond to “discrete events” as needed. At the same time, the base controller can receive the comprehensive optimal control scheme of the middle layer, and execute the control instruction through feedback control to complete the final goal.

In addition, HAVC has some important differences and advantages. In contrast to traditional secondary voltage control schemes, HAVC systems are event-driven, with control instructions responding directly to an event and eliminating it, rather than starting at a set time. This makes the HAVC system more flexible and efficient. In addition, the hierarchical structure of the HAVC system makes the top and middle layers each perform their own duties, and each has its own SCADA system and database as well as analysis and processing software, thus reducing the computational complexity of data analysis and processing, and improving the speed and effectiveness of regulation.

In general, SQ-300i-8700700-004 is an advanced voltage control method for power system, which realizes accurate, efficient and optimal control of power system voltage through comprehensive application of mathematical theory, hybrid system concept and hierarchical control structure.
