Description: 在电力系统中，客户经常提出要实现电力系统监控主接线图的潮流实现。所谓潮流实现即是在电力监控系统的主接线图中能够动态反映各线路的运行情况，包含电流流动方向，各设备运行状态等。由于在水电站监控系统中很多用户提出要求能够反映发电机组的动态运行情况，即在主接线图中能够反映哪个机组正在运行。这里我采用贴图法进行动态贴图然后交替显示达到动态运行的目的。当然我们可以采用其他的很多方法，比如CDC类对象动态绘制等。 -in the power system, customers often made to achieve the main power system control diagram of the trend to achieve. To achieve the so-called trend that is the power of the main monitoring system wiring diagram to reflect the dynamic operation of the lines, including current flow direction, the device operation status. Due to the hydroelectric power system many users requesting units to reflect the dynamic operation, that is the main wiring diagram to reflect what units are running. Here I use dynamic mapping method shows tile then turn to a dynamic operating purposes. Of course, we can use many other methods, such as CDC category Dynamic Object Rendering so. Platform: |

Description: 无功优化IEEE论文With the increased loading of existing power system, the problem of voltage stability
and voltage collapse has become a major concern in power system planning and operation. The

system to improve the voltage profile and also to meet the reactive power requirements at the
AC–DC terminals to facilitate the smooth operation of DC links. The method involves successive
solution of steady-state power flows and optimisation of reactive power control variables with

Description: 优秀论文配套源码。分布式电源的接入使得配电系统从放射状无源网络变为分布有中小型电源的有源网络。带来了使单向流动的电流方向具有了不确定性等等问题，使得配电系统的控制和管理变得更加复杂。但同时，分布式电源又具有提高电网可靠性，绿色节能，等等优点，所以为更好的利用分布式电源为人类造福，我们必须对其进行研究与分析。
本文采取通过利用仿真软件Matlab编写计算潮流程序模拟分布式电源接入配电网的模型进行潮流计算的方法对分布式电源的稳态影响进行探索与分析。
选取了34节点的配电网网络模型，通过对单个以及多个分布式电源的接入位置以及容量的不同情况对34节点配电网的网损以及节点电压状况进行了分析。
-The distributed generation access to distribution system makes passive radial distribution network to active medium-sized power distribution network. It brings uncertainty to one-way direction power flow, etc., and it makes the control and management of the distribution system more complicated. Otherwise, it can bring a lot of benefits, such as more reliable, and it is green power. The distributed generation should be better known , so we can benefits more.
So the program called Matlab was used to compile a program to solve the power flow problem. By this program, we can text which factor can influence the distributed generation’s access to the distribution system.
The IEEE 34 Node model was chosen to be discussed how different factors can influence the power quality. This article analyzes distributed generation’s influence to the distribution system of energy lost and voltage level.

Description: This paper presents the Direct Power Control of
Three-Phase Matrix Converters (DPC-MC) operating as Unified
Power Flow Controllers (UPFC). Since matrix converters allow
direct AC/AC power conversion without intermediate energy
storage link, the resulting UPFC has reduced volume and cost,
together with higher reliability. Theoretical principles of DPCMC
method are established based on an UPFC model, together
with a new direct power control approach based on sliding mode
control techniques. As a result, active and reactive power can be
directly controlled by selection of an appropriate switching state
of matrix converter. This new direct power control approach
associated to matrix converters technology guarantees
decoupled active and reactive power control, zero error
tracking, fast response times and timely control actions.
Simulation results show good performance of the proposed
system. Platform: |

Description: Abstract—Series resonant DC-DC converter with clamped
capacitor voltage exhibits excellent characteristics in forward
operating mode including simple control, high reliability, soft
switching, high power density and inherently limited load fault
current. However, the conventional single angle phase-shift
modulation that works well in the forward mode cannot reverse
the power flow. In this paper, we propose a modulation strategy
for reverse mode operation by utilizing three phase-shift angles
afforded by the two active full bridges of the circuit. We identify
the optimal modulation trajectories in three-dimensional
modulation space and implement a look-up table based
modulator for power flow control. A high-fidelity simulation Platform: |
